by using sulfobetaine derivant as leveling agent and polybasic acid as complexant of interfering ions, the brightener sn-1 for nickel plating is developed.
以磺基甜莱堿的衍生物为整平剂,多元有机酸为干扰离子络合剂,研制了sn-1镀镍光亮剂。
the result showed that cathodic polarization increases with the addition of complexant trisodium citrate and that formation of the alloy deposit is facilitated by addition of sodium hypophosphite.
认为在镇液中加入配体柠檬酸钠可以提高阴极极化,加入次磷酸钠有利于合金镀层的形成。
through choosing citric acid complexant and other auxiliaries, the experimental was carried on treatment of high concentrated h_2s refinery acidic gas by ferric citrate.
通过选择柠檬酸配位剂和其它助剂,研究了柠檬酸铁处理高浓度硫化氢炼厂酸性气体。
metal complexants such as ferrous complexant and cobaltic complexant are common used in this process.
