摘要
Abstract
Carbonate hydroxyapatite (CHAP) synthesized by precipitation method is used as a sorbent to remove hexavalent chromium in solution, and the effects of pH value, adsorption time, adsorption temperature, CHAP dosage on the adsorption result are discussed in the work. The results show that: at room temperature, 5 of pH value of solution, stirring adsorpted 30 min with a certain amount of 5 g/L CHAP, the adsorption removal of Cr6+ basically reach to the equilibrium, the removal is up to 94.16％, the maximum adsorption capacity is to 23.54 mg/g.关键词
