Adsorption of Hexavalent Chrome in Wastewater by Peanut Shell

Article Preview

Abstract:

In order to investigate the adsorption of hexavalent chrome in wastewater by peanut shell, the orthogonal test was designed to find the best adsorption conditions such as pH value, temperature, adsorption time and adsorbent dosage etc. The results show that the peanut shell is a kind of economic and efficient absorbent; hexavalent chrome removal rate can reach more than 85%, when the hexavalent chrome wastewater concentration is 30mg/L, dosing 1g peanut shells into 50mg wastewater, adjusting pH value to 2.0, adsorbing 300min at room temperature.
