Abstract
In this study the eggshell membrane adsorption for chromium, cadmium, copper in the wastewater was investigated through the discussion of the amount of eggshell membrane, adsorption time, adsorption temperature, as well as the removal efficiency under the optimum conditions. The results show that for the Cr6+、Cd2+、Cu2+ in the simulated wastewater solution, the optimum dosage of eggshell membrane were 1.2g、1.0g and 1.2g, the best adsorption time were 45min、30min and 60min, the optimum adsorption temperature were 50°C、70°Cand 70°C, respectively.
