重金属在碱渣层中的分布及形态研究
Distribution and speciation of heavy metals in alkali residue
摘要
Abstract
The adsorption capability of alkali residue to heavy metals ( such as Cu2+ , zn2+ and Cd2+ )was investigated using a self-made dynamic adsorption column. The experimental results show that under the conditions of high concentration and high hydraulic load, the most adsorption quantities of alkali residue to Cu2+ , 2n2+ and Cd2+ can reach 194. 451, 24. 245 , 11. 036 mg/g, respectively, the penetration time can reach over 60 h, and the saturated absorption time can reach more than 80 h.Heavy metal species in alkaline residue were also studied using Tessier extraction. The experimental results show that the heavy metals on the surface of alkali residue are mainly in Fe-Mn oxide form and carbonate-bounded form, hardly in organic-bounded form.关键词
