Abstract

With the increasing spread of pollution, it is essential to focus on removing and reducing the entry of pollutants into the environment using cost-effective and efficient methods. One of the main sources of pollution in aquatic ecosystems is elements in various forms, which, unlike organic compounds, do not decompose in nature through chemical or biological processes and severely affect food webs and ultimately human health. Zinc is one such particle, which, given the varying tolerance levels of aquatic organisms, induces different effects in the aquatic environment. This study aimed to remove chemical, green, and ionic zinc nanoparticles at two concentrations of 1.5 and 2.5 mg/L using a Bit Trap Filter system. Sampling was performed over three hours, every twenty minutes. The efficiency of reducing the concentration of chemical, green, and ionic zinc nanoparticles at an initial concentration of 1.5 mg/L was 98%, 98.67%, and 98.67%, respectively. The efficiency of reducing the concentration of chemical, green, and ionic zinc nanoparticles at an initial concentration of 2.5 mg/L was 98.40%, 99.20%, and 98.40%, respectively. This study demonstrated that chemical, green, and ionic zinc nanoparticles can be removed from the aquatic environment using a Bit Trap Filter system.
