Traditional phosphating solutions usually contain sodium nitrite, potassium bichromate, sodium fluoride and nickel nitrate which are detrimental to human body and environment. 常规磷化液中通常含有亚硝酸钠、重铬酸钾、氟化钠或硝酸镍等对人体和环境有害的物质。
The difference did not change even under the action of sodium fluoride, potassium bichromate, mitomycin C and colchicine. 在氟化钠、重铬酸钾、丝裂霉素C和秋水仙素等四种环境诱变剂作用下,以上倾向没有变化;
A kind of chromium gel system of retarded crosslinking made of partially hydrolyzed polyacrylamide ( HPAM), sodium bichromate and organic reductant sulfocarbamide was investigated. 缓交联铬冻胶体系由部分水解聚丙烯酰胺、重铬酸钠与有机还原剂硫脲组成。
