Abstract:

采用骨炭作为吸附剂,研究其在不同骨炭用量、pH值和温度条件下对水中Sb(Ⅲ)和Sb(Ⅴ)吸附和解吸的影响。结果表明,骨炭对Sb(Ⅲ)的吸附效果远好于Sb(Ⅴ),在0.2~8.0mmol/L的Sb(Ⅲ)和Sb(Ⅴ)浓度下,骨炭对这2种形态Sb的去除率分别为46.1%~78.6%和9.6%~31.7%。采用Langmuir方程和Freundlich方程均可以很好地拟合骨炭对Sb(Ⅲ)和Sb(Ⅴ)的吸附,Sb(Ⅲ)和Sb(Ⅴ)的最大吸附容量分别为110.1034mg/g和17.4167mg/g。骨炭对Sb(Ⅲ)的解吸也大于对Sb(Ⅴ)的解吸。骨炭对Sb(Ⅲ)和Sb(Ⅴ)的吸附受不同骨炭用量、pH值和温度影响。
