PRETREATMENT DEVICE FOR DISSOLVED METAL ION ANALYSIS, DISSOLVED METAL ION ANALYSIS DEVICE AND DISSOLVED METAL ION ANALYSIS METHOD

Japanese Patent JP2017087102

A

PROBLEM TO BE SOLVED: To provide a pretreatment device for dissolved metal ion analysis capable of preparing a sample solution suitable for dissolved metal ion analysis in a short time compared with the conventional one, a dissolved metal ion analysis device and a dissolved metal ion analysis method.SOLUTION: There is provided a pretreatment device for dissolved metal ion analysis, comprising: an electrolytic tank having a space holding a solution containing metal ions; the first and second cation-exchange membranes and the first and second anion-exchange exchange membranes for partitioning the space of the electrolytic tank into the first, second, third, fourth and fifth chambers; and an anode and a cathode. The first chamber is partitioned with the first cation-exchange membrane; the second chamber is partitioned with the first and second cation-exchange membranes; the third chamber is partitioned with the second cation-exchange membrane and the first anion-exchange membrane; the fourth chamber is partitioned with the first and second anion-exchange membranes; and the fifth chamber is partitioned with the second anion-exchange membrane. The anode is arranged at the inside of the first chamber, and the cathode is arranged at the inside of the fifth chamber.SELECTED DRAWING: Figure 1
