连二亚硫酸钠对淹水土壤中p,p'-DDT脱氯过程的影响及机理研究
Dechlorination process and mechanism of p ,p'-DDT in waterlogged soils by dithionite
摘要
Abstract
Dechlorination process and mechanism of p,p'-DDT in soil and dithionite-treated soil by dithionite (200 mmol/L) were investigated under waterlogged culture condition ( soil/water = 2 g/40 mL). Addition of dithionite resulted in dechlorination of p,p'-DDT by 73% and 79% for 2 d in soil and dithionite-treated soil, respectively, and subsequently the dechlorination slowly continued. The p,p'-DDD and p,p'-DDE were identified to be metabolites of p, p'-DDT in dithionite-treated soil. The dithionite was the predominant contributor of dechlorination of p,p'-DDT, and Fe + in dithionite-treated soil also had contribution. Dithionite could be used to develop a remediation option for DDTs-contaminated soils.关键词
