比较两种表面活性剂淋洗去除土壤中的重金属
Washing removal of heavy metals from different soils by two surfactants
摘要
Abstract
Surfactant rhamnolipid and Texapon were investigated to wash heavy metals in parking lot and wetland soil samples taken from a coastal city in our country.The capabilities of heavy metal removal and effect on heavy metal fraction distribution of the two surfactants on soil samples were studied.In addition,toxicities of residue surfactants in soil samples were investigated.It was indicated that both surfactants were able to remove Cu,Cd,Pb,and Zn in the two soil samples.Heavy metal removal by both surfactants from the parking lot soil sample was higher than that from wetland soil sample;and the removal rate of Texapon was higher than that of rhamnolipd.Both surfactants exhibited best removal on the exchangeable fraction of heavy metals,yet minimum removal on residue fractions.The residues of rhamnolipid remained in both soil samples,and Texapon remained in the parking lot sample had low toxicities;while the residue of Texapon in the wetland soil sample was bio-toxic.关键词
