Abstract

The improper disposal of waste water by tannery and coolant oil industries in nearby water sources which contains heavy metals, made us to choose the adsorption process using geo polymer for the heavy metal removal. In the 1^st phase, stock solution for heavy metals like Cu2⁺, Ni2⁺ and Pb2⁺ were prepared. On the other side geo polymer pebbles were also prepared according to the proportions along with. Using geopolymer pebbles, the solution will be retained for certain hours and it will titrated to find out their initial and final ion concentration. Similarly in 2nd phase, Industrial waste water will be retained with the geopolymer pebbles and then they are titrated to find out their initial and final ion concentration. The samples were tested by titration and by Atomic Adsorption Spectrophotometry methods. Those results were also been compared.
