| 英文摘要 | This paper summarizes a study on the application of vertical electric direct-current (DC) to control the migration of metal complexes in soil columns when EDTA/[S,S]-ethylenediaminedisuccinic acid (EDDS) is used to enhance ryegrass uptake of Cu/Zn from contaminated soil. The results show that application of EDTA/EDDS significantly increased ryegrass uptake of Cu/Zn when compared with no EDTA/EDDS application and the Cu/Zn concentrations in all soil solutions sampled at three different levels of the soil column, i.e. 15, 30 and 50 cm. Application of vertical DC electrical field (1.0 V cm(-1)) through top anode (close to the surface) and bottom cathode caused redistribution of Cu/Zn concentrations. Copper/Zn concentrations significantly decreased in soil pore fluid that were sampled in the bottom sections of the column, suggesting an efficient control of the leaching risk of the Cu/Zn complexes when the vertical electrical field is applied. The shoot Cu concentration of ryegrass in the treatments with EDTA/EDDS and electrical field together was 0.46/0.61 times higher than that in treatments without electrical fields.
