By the combination of the method for isolation and concentration by using NH4SH and the calculation RMo at the paper electrophoresis, following injurious nine metals were separated and identified : Hg, Pb, As, Sb, Cu, Zu, Ag, Cd and Bi. Three test solutions for the paper electrophoresis were prepared by the NH4SH method. Cu, Zn, Ag, Cd and Pb, belong to the 1st section, were separated and identified according to RMo by using 1N citric acid, 5N acetic acid and 5N formic acid as the electrolyte for the paper electrophoresis. Hg and Bi, the 2nd section, were separated and identified as stated above by using 0.1M lactic acid or 5N formic acid as the electrolyte. As and Sb, the 3rd section, were separated and identified as stated above by using 0.1M lactic acid as the electrolyte.
