3种表面活性剂对有机氯农药污染场地土壤的增效洗脱修复效应
Effects of Three Surfactants Remedying Organochlorine Polluted Soils Through Enhanced Elution
摘要
Abstract
A batch soil washing experiment was carried out using Tween80, TritonX -100 and SDS, three different kinds of surfactants to elute organochlorine pesticides from contaminated soil. It was found that Tween80, TritonX - 100 and SDS all displayed certain effects, which increased with the application rate of the surfactants. Their effects on chlordane, en-dosulfan and heptachlor were obviously higher than on mirex. The removal effect of TrintonX - 100 on mirex was significantly higher than that of the other two. Treated with Tween80 at 10 g · L-1 , Triton X - 100 at 10 g ? L-1 and SDS at 8. 50 g ? L-1 , the soil reduced its total contamination of the four pesticides by 32. 8% , 59. 7% and 60. 1% , respectively with elevated temperature, the removal rate of OCPs increased. For such contaminated soils, the use of 10 g ? L~ TritonX - 100 was the best after the samples were shaken for 5 minutes at 50 ℃.关键词
