采用 EDI 技术富集痕量重金属，以0.1 mg/L 的 Cu2+溶液为例，研究不同因素对富集过程的影响.结果表明：膜堆在一定条件下存在平衡缓冲区，此区域内具有自我调节能力，确定了最佳操作条件为操作电流190 mA、淡水流量60 mL/min、浓水流量15 mL/min、极水流量15 mL/min；膜堆在此条件进行富集操作稳定性好、重现性高、富集效果显著.

EDI technology was applied to the enrichment of trace heavy metals, based on the copper ion solution which concentration was 0.1 mg/L, the influence of different factors on enrichment process is researched. The results indicate that there is balance buffer of the stack under certain conditions in which has self-regulation ability. Furthermore, the optimum operating conditions parameters are determined. The results demonstrate that the operating current of EDI is 190 mA, feed flow rate is 60 mL/min, concentrated solution flow rate is 15 mL/min, electrode rinse flow rate is 15 mL/min. In this condition for enrichment of operational stability of the stack, high reproducibility and enrichment effect is remarkable.
