Removal of zinc metal by ion exchanger technique using Amberlite IRA-120

Everyone needs access to hygienic water to live a healthy life. Despite being complex, the connection between the water environment and human activities has been thoroughly demonstrated over the past few decades through various study methods. Among the numerous pollutants that contaminate water, zinc is particularly harmful to humans and the environment, including soil and water bodies. The assessment and removal of zinc from water sources are of utmost importance. This paper examines and removes zinc using the ion exchange resin Amberlite IRA-120. The advantage of this resin is that it can be recycled and reused without compromising the quality of water treatment, making it both economical and readily available. The batch experiment is performed at different pH levels, concentrations, and competing ions. under constant conditions to achieve maximum zinc removal at optimum conditions. The regenerated resin is then employed for subsequent removal cycles, demonstrating that the fifth application attains an efficiency of 75%. In the fixed bed column study, it treated more than 6ml/mm 3 of water against zinc. Regeneration of resin is done by regenerating solutions. Resin shows high selectivity to zinc while other metal ions are mixed in the zinc solution. The maximum uptake capacity of this resin is determined at lower pH i.e. 4.5, further study is being done on pH 7 because the study is mainly focused on drinking water. This indicates that even after multiple uses, the upgraded system maintains water quality, allowing for the reuse of treated wastewater.
