Considering the current water scarcity and environmental issues linked with waste water, research into current treatment technologies is critical. Metals, being a highly poisonous substance with suffocating properties, are regarded as one of the environmental pollutants in a wide spectrum of industrial effluents. The current work sought to investigate metal adsorption utilizing TiO2 and ZnO nano absorbent. Two sets of tests are planned to assess metal adsorption performance. Metals are absorbed by TiO2 in the first experimental setup and ZnO in the second. These experiments take place in a batch reactor. The metal removal effectiveness of TiO2 and ZnO is investigated in batch studies utilizing the Response Surface Methodology (RSM). In this study the maximum % reduction of iron is 50.41% at pH 6, contact time 30 min and dosage is 0.04 gm of ZnO nano absorbent. Similarly for chromium it is 36.56 % reduction occurred at pH 6 and contact time 90 min and dosage of 0.08 gm of ZnO absorbent. The ZnO Absorption is effective for metal reduction in batch adsorption process
