Abstract:
Combined with field investigation and adsorption test indoor,the straw biochar were used as the repairing material,and the effect of some factors of the straw biochar adsorption such as the initial concentration of Cu2+,the pH of the solution,the adsorption time and the biochar addition were researched.In order to provide some theoretical basis for the restoration of the copper pollution in the grassland copper mine area.The results showed that the best adsorption pH of straw biochar was 4.5；the adsorption equilibrium time was 8 hours；under the same adsorption conditions,when the carbon amount was 0.5 g,the maximum adsorption capacity was 17.06 mg?g-1.Therefore,when the content of pollutants was less than 512 mg?L-1 in the mining area，the pH was 4.5 of adsorption environment,adding 0.5 g of straw biochar,after 8 hours,that would cost saving and reach an obvious result when used the straw biochar restore and adsorb the Cu2+ in wastewater.
