长期以来,采用剧毒的氰化物作为络合剂的镀铜工艺,在生产中产生大量的有毒废水、废气,危害着我们电镀工人的健康,污染了江河、大气,影响着工农业的生产和人民正常的生活。沿用老工艺排除废水,按规定允许含氰量不超过一千万分之一,饮用水含氰量不应超过一万万分之一。要达到此标准,如果采用污水处理方法,在目前,受技术条件的限制,需耗费巨大的代价。因此,氰化物镀铜的废止是急待解决的迫切问题,用无氰镀铜取代氰化物镀铜有着 For a long time, the use of toxic cyanide as a complexing agent of the copper plating process, in the production of large amounts of toxic waste water, emissions, endangering the health of our plating workers, pollute the rivers and the atmosphere, affecting the production of industrial and agricultural people normal life. Follow the old process of removing waste water, according to the regulations to allow cyanide content does not exceed one ten millionth, drinking water cyanide content should not exceed one ten millionth. To achieve this standard, if the sewage treatment method, at present, subject to technical constraints, it will cost a huge price. Therefore, the abolition of cyanide copper plating is an urgent problem to be solved, with cyanide-free copper plating instead of cyanide copper
