    • To efficiently recover heavy metal ions from an electrolyte by using one of sulfoxylic acid, dithionous acid, sulfurous acid, pyrosulfurous acid, pyrosulfuric acid, peroxosulfuric acid, peroxodisulfuric acid, polythionic acid and hydrosulfurous acid as a reducing agent. Stainless steel 1 is dipped into an electrolytic bath using a neutral salt aq. Solution of sodium sulfate as the electrolyte 21 and is descaled by electrolysis. The electrolyte 21 in the electrolytic bath 2 is received in a reducing vessel 4 through a reserve tank 3. The electrolyte 21 in the reducing vessel 4 is adjusted in pH to 1-2 by adding sulfuric acid and sodium hydroxide and is reduced by adding an acid or a metallic salt of the acid. Sodium hydroxide is added into the reduced electrolyte 21 transported to a neutralizing vessel 5 to make pH 5 and to convert the heavy metal into the hydroxide. The electrolyte 21 is passed through a precipitator 6 and a filter 7 to remove the heavy metal and is fed to the reserve tank 3 as the clean electrolyte 21.
    • 通过使用次硫酸,连二亚硫酸,亚硫酸,焦亚硫酸,焦硫酸,过氧硫酸,过氧二硫酸,多硫酸和氢亚硫酸中的一种作为还原剂,从电解质中有效地回收重金属离子。 使用中性盐水将不锈钢1浸入电解槽中。 硫酸钠溶液作为电解质21并通过电解除垢。 电解槽2中的电解质21通过储罐3接收在还原容器4中。通过添加硫酸和氢氧化钠将还原容器4中的电解质21调节至pH 1-2,并通过添加 酸或酸的金属盐。 将氢氧化钠加入到输送到中和容器5中的还原电解质21中以使pH为5并将重金属转化成氢氧化物。 电解质21通过除尘器6和过滤器7以去除重金属并作为清洁电解质21被输送到储存罐3。
