When pH is 10, adsorption time is 30 min, dosage of bone char is 0.6 g/L, the original concentration of As in drinking water is 0.5 mg/L, As removal can reach 95.2%. The adsorption behavior is fitted both with Langmuir and Freundlich isotherm. The adsorption mechanism is supposed to be Ca—OH functional groups combined with anion. And there may occur the co-precipitation between calcium hydrogen arsenate and hydroxylapatite in the aqueous solution, and ions also exchange. The saturation adsorption capacity of As reaches 4.688 mg/g. Indexes of effluent are in good agreement with the WHO stringent drinking water standards (0.01 mg/L).
研究结果表明:在pH=10,吸附时间为30 min和骨炭加入量为0.6 g/L,饮用水砷初始质量浓度为0.5 mg/L时其砷去除率可达95.2%;骨炭吸附砷的行为同时符合Langmuir和Freundlich等温吸附模型;其吸附机理可能是Ca—OH官能团结合HASO4阴离子,并产生砷酸氢钙和羟基磷灰石的共沉淀,另外还存在离子交换作用;吸附柱的饱和吸附容量为4.688 mg/g;出水砷浓度符合世界卫生组织规定饮水砷标准(0.01 mg/L)。
