Abstract
This study introduces an eco-friendly approach to detect and remove Co(II) ions from electroplating effluents and lithium-ion battery wastes using a cobalt nanosensor (CNS). A repurposed cellulose template which was recovered from wastepaper (CNFsWP) was decorated with 1-(2-hydroxy-1-naphthylazo)-2-naphthol-4-sulfonic acid (HNNSA) ligand molecule, resulting in a highly sensitive and selective CNS. Through rigorous optimization, the CNS's performance is maximized by considering factors like pH, sensor amount, reaction time, probe concentration and temperature.
Advanced characterization techniques, including XRD, SEM, TEM, and nitrogen adsorption, confirm the porous structure of the cellulose carrier, crucial for efficient cobalt ion capture. DFT calculations further explain the molecular interactions between the cellulose and Co(II), validating the selective binding mechanism.
The fabricated CNS demonstrates an exceptionally low detection limit for Co(II) down to 1.13 × 10−7 M, making it a talented candidate for practical applications in electroplating wastewater treatment. This sustainable solution offers a significant step towards mitigating heavy metal contamination and promoting environmental sustainability.
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
