摘要
利用硫氰酸铵对螺旋藻进行改性制备新型吸附剂吸附Cr6+研究。结果显示:硫氰酸铵同一氯乙酸的质量比为1:0.6,藻类投加量为0.8g,初始pH为0,改性时间为2h,改性温度为60℃时,改性后螺旋藻对六价铬的吸附效果最好。并对原藻和改性后的藻吸附能力进行对比研究。结果显示:对于100mL的Cr6+溶液浓度为14mg/L的溶液,硫氰酸铵改性后的藻吸附六价铬效果最好。
Studied on the new absorbent by modified spirulina with ammonium thiocyanate using for hexavalent chromium recovery.he experimental results show the best conditions were that the mass ratio of ammonium thiocyanate and chloroacetic acid was 1：0.6,the dosages of spirulina was 0.8g,initial pH was zero,modified time was 2h and modified temperature was 60℃ to Cr6＋ initial concentration was14mg/L 100mL.Contrast studied the adsorptive capacity of raw spirulina and modified spirulina.The results show when initial concentration was 14mg/L 200mL,the modified spirulina adsorption Cr6＋ capacity was best.
