There is a rising genuine danger to the earth from unpredictable arrival of heavy metals into the wastewaters and soil from human modern practices. In this examination, the take-up of chromium and nickel, being among the significant toxins from our industries, by thermally and artificially activated groundnut shell powder was investigated. The impacts of various states of contact time, adsorbate dosage, mixing speed, pH and initial concentration on adsorption process were studied. The adsorbent materials were characterised by SEM, XRD and EDS. The adsorption procedure of chromium and nickel particles onto both the thermally and artificially activated groundnut shell powder is in great concurrence with the Langmuir adsorption isotherm and Freundlich adsorption isotherm.
