镀铬的废水和铬雾严重地污染生态环境,毒害操作工人的身心健康。为此,研究用毒性较小的三价铬盐溶液来代替现用的毒性较大的六价铬(铬酐)电镀,是70年代兴起的新动向。英国的阿尔布赖特—威尔逊公司率先推出专利产品三价铬电镀液,继而美国、日本的镀液生产厂也陆续将三价铬镀液投放市场,英国的非铁金属研究协会还专门向西欧各国推荐使用三价铬
Chromium plating wastewater and chromium fog seriously pollute the environment, poisoning the physical and mental health of workers. To this end, the study of the less toxic trivalent chromium salt solution to replace the existing toxicity of hexavalent chromium (chromic anhydride) plating, is the rise of the 70’s new trend. British Albright - Wilson took the lead in the introduction of patented trivalent chromium plating solution, followed by the United States, Japan, bath manufacturers have also put the trivalent chromium plating solution on the market, the British non-ferrous metals Research Association also specifically to Western Europe Countries recommend the use of trivalent chromium
