In order to explore the best conditions and techniques, and increase the chromium-contaminated wastewater purification effect, the adsorption of Cr (Ⅵ) onto tannery sludge has been investigated. It can solve the tannery sludge treatment problem, realize waste utilization of resources, and can also lower the treatment costs of chromium-contaminated wastewater. It was found that, with the increasing concentration of Cr6+, the sludge adsorption capacity increased;the best pH of adsorption is 3 and the best shaking time is 30 min;the old sludge is of better adsorbability than the new sludge.
