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5~15 V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15 V,初始土壤pH 3,β-环糊精的加入量3 g,NaCl加入量5 g。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.
