Pollution caused by dangerous substances, including heavy metals, is currently one of the most significant ecological concerns and public health issues. The removal of these materials from soil and water poses a significant decontamination challenge. The pollution of environment due to improper disposal of wastewater without treatment caused different types of pollution and it also affects the functioning of the ecosystem. The discharge from numerous industrial procedures, such as electroplating and tannery operations, a range of chemical contain, such as alkaline and acidic cleaners, electro-cleaners, and pickling solutions. The removal of metal ions can be treated by unit operation or unit process technique of wastewater treatment, sulfide precipitation, ion exchange, and evaporation are found to be effectively for most of the effluent treatment. Existing wastewater treatment techniques involve more time, cost and coagulants etc., these are becoming redundant nowadays due to several reasons. Adsorption techniques are commonly employed for treating industrial wastewater, particularly aqueous streams. This study aimed to evaluate the efficacy of a Nano adsorbent in removing metal ions from industrial effluents. The nanoparticles are used, such as zero valent iron, titanium dioxide, and magnetite, as medium which decreases has become more prevalent due to their low operating and maintenance costs. Additionally, their obtainability, potency, and has sustain to degrade pollutants have result in their increasing usage. The study seeks to investigate the effectiveness of the Nano adsorbent in treating various industrial effluents with varying wastewater concentrations. Using different kinds of Nano adsorbent in several trails it was observed that these Nano adsorbents are effectively functioning in the removal of heavy metal compounds, like lead and chromium. Based on study it was clear from the SEM analysis, the heterogeneous nature of Nano adsorbent gives good adsorption of Cr by porosity of surface texture. The Nano adsorbent in the form of titanium dioxide was found to be potency in removing the heavy metal compounds from the industrial discharge as it has an potency of 89–97%. Based on the several trails it was evident that the Nano adsorbent found to be effective in treatment of heavy metals from the industrial effluent.
