中文摘要: 开展了新型除钴有机试剂净化后的新液与使用锌粉、锑盐、硫酸铜净化后的新液进行锌电解对比研究。结果表明,使用新型除钴有机试剂净化后的新液进行锌电解,在电流密度320 A/m2、槽电压3.15~3.3 V、槽温28~31 ℃、时间32 h、明胶溶液每2小时10 mL、新型有机除Co试剂用量8.5 mg/L的条件下,电解过程中锌片外观质量较好,槽面无返溶烧板现象,电流效率86.09%~89.22%,电流效率高出8.35个百分点;随着电解周期的延长,有机物不断富集,电解阴极出现返溶、烧板迹象,但随着活性炭的加入,返溶、烧板现象停止,阴极锌片表面平整光滑。
Abstract:Comparative study on zinc electrolysis from new solution of cobalt removal purified by zinc powder, antimony salt, copper sulfate, and new organic reagent for cobalt removal was carried out. The results show that zinc plate with good appearance quality is obtained from new solution purified by new organic reagent, without phenomenon of re-dissolution and plate-burning, and current efficiency is 86.09%~89.225 with 8.35 points higher than that of other purification methods under the optimum conditions including current density of 320 A/m2, cell voltage of 3.15~3.3 V, tank temperature of 28~31 ℃, time of 32 h, dosage of gelatin solution of 10 mL every two hours, and dosage of new organic reagent of 8.5 mg/L. Organic matter accumulates continually, re-dissolution and plate-burning of electrolytic cathode appear with prolonging of electrolysis duration, but stop after active carbon addition, and cathode zinc plate has flat and smooth surface.
