Highly efficient iodine capture and selective adsorption and removal of cationic dyes by using a copper-based coordination polymer decorated over graphene oxide and carbon nanotubes
This study focuses on synthesizing hybrid nanocomposites (HNCs) through a one-step solvothermal method, combining highly crystalline and evenly dispersed copper-based coordination polymer (Cu-CP), graphene oxide (GO), and carbon nanotubes (CNTs). Extensive characterization using elemental analysis, SEM, TEM, EDX, XRD, FT-IR, Raman spectroscopy, TGA, and crystallographic studies confirm the properties of the nanocomposites, with PXRD investigation supporting their clear crystalline structure. Morphological and elemental studies reveal effective adsorption of copper-benzoic acid-containing Cu-CP onto GO and CNT substrates. The synthesized nanocomposites exhibit superior adsorption capacity for iodine (I2), a model radioactive pollutant, attributed to decreased CP size and larger surface area. The strong affinity for I2 arises from various interactions, including conjugated π-electron aromatic systems and halogen bonds. Cu-CP, Cu-CP@GO, and Cu-CP@CNT adsorbents efficiently extract toxic iodine from hexane solution, achieving a substantial capture capacity of 347.85 mg/g over 24 h. In the vapor phase, Cu-CP@GO exhibits an even higher capacity (951.52 mg/g within 25 h). Moreover, the application of Cu-CP, Cu-CP@GO, and Cu-CP@CNT in environmental protection showcases their efficacy in removing cationic and anionic dyes, particularly highlighting remarkable cationic dye selectivity through cation-π and π-π interactions. This research underscores the promising potential of these HNCs in addressing environmental challenges and pollutant remediation.
期刊介绍:
The Journal of Water Process Engineering aims to publish refereed, high-quality research papers with significant novelty and impact in all areas of the engineering of water and wastewater processing . Papers on advanced and novel treatment processes and technologies are particularly welcome. The Journal considers papers in areas such as nanotechnology and biotechnology applications in water, novel oxidation and separation processes, membrane processes (except those for desalination) , catalytic processes for the removal of water contaminants, sustainable processes, water reuse and recycling, water use and wastewater minimization, integrated/hybrid technology, process modeling of water treatment and novel treatment processes. Submissions on the subject of adsorbents, including standard measurements of adsorption kinetics and equilibrium will only be considered if there is a genuine case for novelty and contribution, for example highly novel, sustainable adsorbents and their use: papers on activated carbon-type materials derived from natural matter, or surfactant-modified clays and related minerals, would not fulfil this criterion. The Journal particularly welcomes contributions involving environmentally, economically and socially sustainable technology for water treatment, including those which are energy-efficient, with minimal or no chemical consumption, and capable of water recycling and reuse that minimizes the direct disposal of wastewater to the aquatic environment. Papers that describe novel ideas for solving issues related to water quality and availability are also welcome, as are those that show the transfer of techniques from other disciplines. The Journal will consider papers dealing with processes for various water matrices including drinking water (except desalination), domestic, urban and industrial wastewaters, in addition to their residues. It is expected that the journal will be of particular relevance to chemical and process engineers working in the field. The Journal welcomes Full Text papers, Short Communications, State-of-the-Art Reviews and Letters to Editors and Case Studies
