| 摘 要： | 以阳离子交换膜为隔膜,电解处理塑料粗化过程中产生的废铬酸液。大大优于陶瓷隔膜电解法。离子交换膜法的条件:在温度40～50℃,槽电压2.5～3.0 V的条件下,控制〔Cr3++〕下限值10g/L。电解过程的电流密度为3.5～4.0A/dm2,电流效率可达72%～80%,电耗仅为150～170 kW·h/m3。

| Abstract: | The problem discussed in this article is the disposal of waste chromic acid solution produced from the plastic roughing by diaphragm electrolysis in which the diaphragm is used as the cation exchange membrane. On the conditiorr that the temperature is at 40—50℃, the applied voltage is 2.5—3.0 V, and the least value of Cr3++] is controlled at 10g/L, the current density is 3.5—4.0A/dm2, the current efficiency reaches 72%—80% and the electric energy consumption is only 150—170 kW·h/m3. The new technique has a great advantage over the ceramic diaphragm electrolysis. |
