| 摘 要： | 以氯化镁和造纸草浆黑液为原料,采用物理活化法制得＂氧化镁/活性炭＂新型吸附剂,其比表面积（BET）为388.96 m2/g、总孔容积为0.40 mL/g。测定了这种吸附剂对水中Cr（Ⅵ）的吸附性能,考察了吸附时间、pH值、吸附剂投加量、初始浓度等因素对Cr（VI）的吸附量和脱除率的影响,研究所得吸附水溶液中Cr（Ⅵ）的最佳条件为：吸附时间为120min,吸附剂投加量为2 g/L,pH值为2。＂氧化镁/活性炭＂新型吸附剂对Cr（Ⅵ）的吸附过程符合Freundlich等温式。

| Abstract: | A noval adsorbent from straw pulp black liquor and magnesia chloride was made by physical activation.The results show that the BET surface and total pore volume reach 388.96 m2/g and 0.40 mL/g respectively.The effects of adsorption time,pH,adsorbent dosage and initial concentration were investigated.The best absorption effect was acquired at pH value 2,adsorbent dosage 2 g/L,adsorption time 120 min.The adsorption of Cr（Ⅵ） follows Freundlich isotherm. |
