2-羟基-1,4-萘醌在土壤中降解作用和淋溶行为研究
Degradation and Leaching of 2-hydroxy-1,4-naphthoquinone in Soil
摘要
Abstract
The indoor simulation and soil column method were used to study the degradation and leaching of 2-hydroxy-l,4-naphthoquinone in soil. The results showed that the degradation half-life of 2-hydroxy-l,4-naphthoquinone in sterilized soil and non-9terilized soil was 3.47~6.98 d and 0.42-0.53 d, respectively, and increased with the increasing concentration of 2-hydroxy-l,4-naphthoquinone, indicating that microbial degradation was the dominant. According to the POPs convention, 2-hydroxy-l,4-naphthoquinone belonged to an organic chemical that was degraded easily. The study on leaching of 2-hydroxy-l,4-naphthoquinone in soil showed that 2-hydroxy-l,4-naphtho- quinone was not detected in soil when the initial concentrations were 5 mg·kg-1and 10 mg·kg-1. However, it was detected only in the 0-10 cm depth of soil when the concentration of 2-hydroxy-l,4-naphthoquinone was 20 mg·kg-1. Compared with the non-aged soil, the leaching of 2-hydroxy-l,4-naphthoquinone was weaker in aged soil.关键词
