adsorption for the purpose of the removal chromium(vi) pollutants in water

The removal of the cr(vi) in wastewater is a critical because of its pisonousness and probable accumulation in the environment [1,2]. cr(vi) has been classified as the priority contaminants through the us environmental protection agency [3]. world health organization has set the permissible pollutants level for cr(vi) at 0.1ppm in drinking water [4]. exposed to such as chemicals can harm the central blood system, kidney, and respiratory system in case into human body. in recent years, adsorption has been successively employed in industrial procedure and wastewater treat involving cr(vi) removal. in this study magnetic activated carbon/cobalt synthesized and examination for cr(vi) ions removal. all parameters resulting the removal effectiveness such as ph, analyte concentration and adsorbent dosage, contact time was evaluated by uv-vis spectrophotometer. the results showed that nanocomposites can be employed as a new adsorbent which has higher adsorption capacity and rapid adsorption rate in order to removal of cr(vi).
