Unfortunately, <em>mango</em> leaves are generally dumped as agricultural waste due to their abundance, resulting in significant waste and environmental pollution. In this study, electrochemical and weight loss techniques were utilized to investigate the inhibitory mechanism of <em>mango</em> leaves extract (MLE) on the corrosion of X70 steel in 1 M HCl. The results indicated that MLE was an excellent corrosion inhibitor for X70 steel to resist corrosion in an acidic environment, and the inhibition efficiency was effectively improved by increasing the inhibitor concentration and decreasing the temperature. Electrochemical tests have shown that MLE functions as a corrosion inhibitor with a mixed-type mechanism. Fitting the adsorption isotherm with electrochemical data, confirmed that MLE demonstrates corrosion resistance on metal surfaces through adsorption, and this adsorption conforms to the Langmuir isotherm. The adsorption phenomenon was deeply investigated by using atomic force microscopy (AFM) and scanning electron microscopy (SEM). MLE is further proven to interact with the steel surface to generate an adsorption layer that prevents steel corrosion in an acidic environment. In particular, the density-functional tight-binding (DFTB) calculations results also suggest that the π electron and lone-pair electrons in the main components of MLE are conducive to enhancing the adsorption of corrosion inhibitor molecules on the iron surface, to achieve a more effective inhibition effect. Furthermore, the toxicity prediction indicates that the MLE components are nearly non-toxic, which complies with environmental protection regulations. MLE has excellent corrosion resistance, with a corrosion inhibition efficiency of nearly 90 % at a concentration of 400 mg/L, while also helping to solve agricultural waste management challenges.</div></div>","PeriodicalId":22097,"journal":{"name":"Sustainable Materials and Technologies","volume":"42 ","pages":"Article e01167"},"PeriodicalIF":8.6,"publicationDate":"2024-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142592646","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Solid leaching generates acidic effluents that can be pre-treated using precipitation steps for partial separation before applying sorption for metal recovery from mild acidic solutions. For this purpose, a new sorbent was designed carrying numerous N- and S-bearing reactive groups with good affinity for platinum (as chloroanionic species). Thiazole precursors were first reacted before being grafted (by free radical reaction) with triallyl cyanurate (to form CTTR sorbent). The material was characterized by a series of analytical tools (SEM, BET, FTIR, XPS, TGA, elemental analysis, and titration). The effect of pH combined with FTIR and XPS spectroscopy analyses allowed identifying the mechanisms involved in metal binding: electrostatic attraction of chloroplatinate anions with protonated amine groups (especially in acidic conditions), while at moderate acidic pH, metal sorption proceeds through ligand exchange and chelation onto N-based and S-based groups. Optimum sorption was found at pH close to 4 (near pH_pzc value). Under selected experimental conditions, the equilibrium was reached in 25–35 min. The pseudo-first order rate equation fitted well experimental profile (though the resistance to intraparticle diffusion contributed to the kinetic control). The maximum sorption capacity at room temperature reached up to 1.58 mmol Pt g⁻¹ (at pH 4). The sorption isotherm was successfully fitted by the Temkin equation. The sorption is spontaneous and exothermic (with reduction in maximum sorption capacity reaching up to 25 %, when temperature increases to 50 °C). Optimum platinum desorption was obtained with 0.3 M HCl solution (with solid/liquid ratio 1.67 g L⁻¹) for complete desorption and enrichment factor close to 4.6. Complete desorption was maintained over 5 cycles, while the sorption efficiency decreased by less than 3.5 % at the fifth cycle. The sorbent showed remarkable stability for PGMs (Pd(II) in addition to Pt(IV)) against alkali-earth elements or base metals (from equimolar synthetic solutions); the selectivity is driven by the preference of the reactive groups (soft base and intermediary base) for soft PGM metals against hard and borderline metal ions; this selectivity is also affected by metal speciation (formation of chloro-anionic species). The valorization of platinum from non-compliant Pt/Al₂O₃ catalyst was investigated after leaching with aqua regia. Platinum was precipitated from the leachate with ammonium chloride. In a second step, aluminum was removed by precipitation at pH 5. The residual solution was then treated by adsorption on CTTR: optimum separation between Pt and Al was achieved at pH ≈ 3.</div></div>","PeriodicalId":22097,"journal":{"name":"Sustainable Materials and Technologies","volume":"42 ","pages":"Article e01165"},"PeriodicalIF":8.6,"publicationDate":"2024-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142655998","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Accordingly, chitosan-based hybrid hydrogel beads were fabricated by incorporating naturally available siliceous micro- and nanoparticles, namely diatomite and bentonite, with different mass ratios. Morphology, swelling behavior, mechanical stability, and ultimately, Methylene Blue (MB)-adsorption performance of the hydrogel beads were comprehensively evaluated in terms of filler dispersion and interactions between the fillers and the matrix. Results revealed that while the simultaneous incorporation of inorganic additives inside the chitosan backbone reduced the swelling degree, the mechanical stability was significantly ameliorated when the 1:1 diatomite-bentonite mass ratio was exploited inside the chitosan matrix. That can be attributed to the well-dispersed fillers and enhanced mechanical entanglements, as well as the strengthened physical interactions between diatomite-bentonite and chitosan matrix. When the hybrid filling system was applied, MB removal efficiency increased synergistically by over 246 % compared to bentonite alone and 268 % compared to diatomite alone, even at low MB concentration (10 ppm). The MB adsorption kinetics and isotherm were also studied. The adsorption kinetics of MB were well-fitted for all compositions using the pseudo-second-order model. The isotherm data for optimum beads indicate that the Freundlich isotherm model provided the best fit, suggesting the multilayer adsorption with a non-uniform distribution of adsorption heat.

The major focus was the incorporation of sustainability measures such as integrating life cycle assessment (LCA) into the materials development at an early stage to study and compare the environmental feasibility of the recycled membrane with the primary membrane. The aim was also to ensure reduced resource depletion of critical raw materials such as cobalt and lanthanum by means of recycling. It consisted of microwave-assisted dissolution of the membrane followed by ultrasonic spray synthesis. The recycled membrane exhibited at least 83 % of the oxygen permeability of the primary membrane and maintained hydrogen tolerance up to 600 °C for 25 h which is a remarkable result for LCCF_6428 in terms of potentially enhancing its life span. As per the LCA, recycling did result in lower resource depletion. However, the recycled LCCF had a higher overall environmental impact compared to the primary LCCF, mainly due to increased electricity consumption during recycling.

The leakage of the molten phase limits the use of PCMs, but it can be alleviated by impregnation into porous matrices. Metals can be used for high temperature stationary heat storage, but are incompatible with oxide matrices due to the large difference in density and surface tension.
