铜-菲复合污染在腐植酸洗提中的溶出特性及交互作用
摘要
以腐植酸作表面活性剂
洗提修复铜-菲复合污染土壤
研究了腐植酸对Cu2+和菲的单一溶出特性
Cu2+和菲的复合污染对腐植酸洗提污染土壤时的交互作用。结果表明
腐植酸对Cu2+和菲具有较好的洗提吸附性能
当腐植酸加入量为5 mg/g土壤时
复合污染土壤中铜离子饱和溶出量可达516.6 mg/kg以上
菲最大溶出量为569.1 mg/kg。无论有无Cu2+的存在
腐植酸对菲都具有较好的淋溶效果
菲的溶出量基本不受到Cu2+的影响
而菲的加入对Cu2+的溶出具有一定的颉颃作用。
Abstract
Humic acid was used to remove the copper ion and phenanthrene from contaminated soil as surfactant.Cu2+ and phenanthrene were selected as objects to study characteristics stripping by humic acid.The interaction of Cu2+-phenanthrene was discussed in contaminated soil.The results showed that humic acid had good stripping properties for Cu2+ and phenanthrene.The stripping quantities of Cu2+ and phenanthrene in compound contaminated soil were respectively 516.6 mg/kg and 569.1 mg/kg when the humic acid addition...
