| 摘 要： | 以4，4′-二溴联苯醚(BDE-15)为研究对象，探讨了电极电压、初始土壤pH、β-环糊精加入量、NaCl加入量等工艺条件对多溴联苯醚在土壤中迁移效果的影响。实验结果表明:在电极电压为5~15V范围内，随着电极电压的升高，土壤中BDE-15的迁移效果增强;初始土壤为酸性时、加入β-环糊精或NaCl后，土壤中BDE-15的迁移效果均增强。本实验选择的最佳工作条件为:电极电压15V，初始土壤pH3，β-环糊精的加入量3g，NaCl加入量5g。

| Abstract: | Taking 4,4′-dibromodiphenyl ether (BDE-15) as the research object,the factors affecting the migration of polybrominated diphenyl ethers (PBDEs) in soil were studied,such as:electrode voltage,initial soil pH,β-cyclodextrin dosage and NaCl dosage. The experimental results show that:In the electrode voltage of 5–15 V,the migration effect of BDE-15 in soil is improved with the rising of electrode voltage;when the initial soil is acidic,or β-cyclodextrin or NaCl is added,the migration effect is also improved. The optimum process conditions are as follows:electrode voltage 15 V,initial soil pH 3,β-cyclodextrin dosage 3 g,NaCl dosage 5 g. |
