  • 摘要: 以2,2',5,5'-四氯联苯(PCB52)为典型代表,采用微波提取法研究了土壤中多氯联苯的锁定效应及其影响因素.实验表明,老化时间、土壤的有机质含量、含水率、pH值以及老化环境温度都对土壤锁定2,2',5,5'-四氯联苯的效果有显著影响.2,2',5,5'-四氯联苯锁定量随着老化时间的增长而增加,添加20 d后尤为显著,之后变化缓慢,趋于平衡;随着土壤有机质含量的增加而显著增加;随着土壤含水率的增大而下降,且表现出一定的线性相关性;在pH 5.5-10.5范围内,随着土壤pH值的升高而增大;在15℃到40℃范围内随着老化环境温度的升高而降低.此外,多氯联苯自身的性质也会影响土壤对其的锁定效果.
    Abstract: Taking 2,2',5,5'-tetrachlorobiphenyl (PCB52) as a test compound and using microwave extraction method, the sequestration of PCBs in soil and its influencing factors were studied in this paper. It can be concluded that aging time, soil organic matter (SOM), soil moisture content, soil pH and environment temperature all had significant effects on the sequestration of PCBs in soil. The sequestration of PCB52 in soil first increased greatly along with the aging time, and then changed slightly and tended to balance after 20 d of aging; It increased obviously with the SOM content in the soil and showed a negative correlation to the soil moisture. It also increased with soil pH from 5.5 to 10.5, and increased with environment temperature from 15℃ to 40℃.
