HLDH was synthesized utilizing the co-precipitation technique in this work to demonstrate its applicability for the removal of direct sky-blue dye via an adsorption procedure. The effects of pH, dose, contact time, initial dye concentration, and temperature on the direct sky-blue dye adsorption efficiency were thoroughly investigated. The adsorbents were analyzed using scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FTIR), X-ray powder diffraction (XRD), energy dispersive X-ray (EDX), and Brunauer–Emmett–Teller (BET). Under the best conditions, the maximum adsorption capacity has been achieved for Mg–Cr–Cl (42.95 mg/g) > Zn–Al–CO3 (39.76 mg/g) > Mg–Fe–Cl (38.08 mg/g). The adsorption of dyes on Mg–Cr–Cl, Zn–Al–CO3, and Mg–Fe–Cl followed a pseudo-second-order kinetic model and exhibited Langmuir-type monolayer adsorption. The influence of temperature was studied to determine the thermodynamic parameters. The estimated results showed spontaneous and exothermic adsorption processes. Electrolyte enhances the adsorption capacity to some extent, while surfactants block the sites, thus reducing the adsorption capacity. The maximum desorption of dye was influenced by the sodium hydroxide solution. The research described here might be utilized to create novel adsorbents with improved adsorption capacities for preserving the aquatic environment.Keywords: Adsorption–desorptiondirect sky-blue dyeMg–Cr–Cl HLDHMg–Fe–Clthermodynamic parametersZn–Al–CO3 AcknowledgmentThe authors would like to extend their sincere appreciation to the acknowledgment; research supporting project (RSP-2023/95, King Saud University, Riyadh, Saudi Arabia).Author contribution statementAhsan Maqsood: Methodology, Writing- original draft, Ruba Munir: Methodology, Formal analysis, acquisition of data, Saima Noreen: Supervision, Conceptualization, Formal analysis, Resources, Gadah Albasher: Conceptualization, Resources, Writing-review& editing, Amna Muneer: Statistical analysis, Writing-review & editing, Murtaza Sayed: execution, Writing-review& editing, Muhammad Yaseen: interpretation, Writing-review& editing, Fazila Younas: Conceptualization, interpretation, Raziya Nadeem: Conceptualization, interpretation, Muhammad Zahid: execution, Writing-review& editing, Nazish Jahan: execution, Writing-review& editing.Consent for publicationAll authors have read and approved this manuscript.Consent to participateNot applicable.Data availabilityData will be made available on reasonable request.Disclosure statementThe authors declare no competing interests.Ethical approvalResearch does not involve Human Participants or/and Animals.","PeriodicalId":9725,"journal":{"name":"Chemical Engineering Communications","volume":"286 8","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135475333","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Then, a double-diffusion heat and mass transfer model between the grain pile and the interstitial air was established based on the local mass and thermal non-equilibrium (LMTNE) mechanism. Finally, employing particle-resolved computational fluid dynamics (PRCFD), the heat and mass transfer between the grain kernels and air during the drying process in the four packed beds were numerically resolved. It was found that the packed bed formed by stacking particles of different diameters had a minimum porosity of 0.4547. The radial porosity of the packed bed oscillates and decreases toward the central axis, while the tortuosity of the airflow path oscillates and decays toward the periphery. The mass transfer Biot number for soybean kernels with diameters of 6.4, 6.8, and 7.4 mm were 2.38 × 106, 2.44 × 106, and 2.53 × 106, respectively. This indicates that the mass transfer rate in the grain pile primarily depends on the magnitude of the moisture diffusion coefficient within the grain kernels. Compared with mass diffusion, thermal diffusion occurs much faster, which results in temperature gradients in packed beds only existing in the first 5 min of drying, and the drying rate in the early stage is higher than that in the later stage. Most importantly, the airflow characteristics, heat and moisture content are not in local equilibrium in the packed bed, and should be considered when designing drying systems.Keywords: Biot numberdouble-diffusionheat-moisture coupling transferporositysoybeantortuosity Disclosure statementThe authors declare that they have no conflicts of interest.Additional informationFundingThis study was supported by the Scientific and Technological Innovation Project for Youth of Shandong Provincial Colleges and Universities (Grant No. 2019KJH012).

As a result of this, huge volume of effluent is being generated from the industrial processes and released into the water bodies. These anthropogenic activities are often detrimental to human and aquatic lives. In this study, a modeling approach to evaluate the photocatalytic degradation of organic pollutants from industrial wastewater using spinel oxide is investigated. Four machine learning algorithms namely, linear regression, decision tree ensemble, medium Gaussian support vector machine, and exponential Gaussian process regression were employed. The parametric analysis of the predictors (particle size of the spinel oxides, the initial dye concentration, the amount of photocatalysts, the band gap, and the irradiation time) and the targeted output of the photocatalytic degradation efficiency shows that a non-linear relationship exists between the predictors and the targeted output. This was further confirmed by the linear regression model with R2 of 0.220. Besides, the decision tree ensemble and medium Gaussian support vector machine regression offer poor performances in predicting the photocatalytic degradation efficiency as indicated by R2 of 0.420 and 0.490, respectively. A superior performance in predicting the photocatalytic degradation efficiency was displayed by the exponential Gaussian process regression with R2 of 0.991.Keywords: Degradationdyemachine learningspinel oxidesupport vector machinewastewater AcknowledgmentsThe authors acknowledge the support of Department of Chemical Engineering, University of Technology, Iraq.Disclosure statementNo potential conflict of interest was reported by the author(s).","PeriodicalId":9725,"journal":{"name":"Chemical Engineering Communications","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136032662","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, these high-value compounds are lost during conventional refining. These phytonutrients can be separated and recovered from crude palm oil (CPO) through methods which prevents the degradation of these compounds. This study evaluated the integrated approach of molecular distillation and adsorption, with the aim of deacidifying and separating vitamin E and carotenoids from CPO, allowing their recovery. Wiped-film molecular distillation (WFMD) was used for deacidification and vitamin E enrichment, the best results were obtained at 200 °C and 21 mL/min. The distillate stream was enriched 937.8% in vitamin E, and the residue stream (named deacidified palm oil - DAPO), enriched in carotenoids, reached 0.1% free fatty acids (FFA). Integration with the adsorption process achieved a carotenoids removal of 79.4% from the DAPO stream. Moreover, the kinetic constant (k2) of adsorption increased by around 87% for DAPO, a result attributed to the absence of fat crystals on the adsorbent surface verified by scanning electron microscopy. Notably, the integrated process approach used is an innovative methodology for the vegetable oil industry presenting an alternative route that allows the preservation and recovery of phytonutrients, and the oil deacidification.Keywords: Bioactive compoundsenrichmentfood ingredientsintegrated processpalm oilphytonutrients AcknowledgmentsThe authors thank Bioesans Biotechnological Products S.A. for financial support and Itochu Chemicals America Inc. for adsorbent donation.
