【摘要】 <正> 线性滴定法是五十年代初由Gran首先提出的一种新的容量分析法,六十年代后期,Ingman-Johansson等人的改进使其更臻完善,本文将该法引入镀铬液的分析中,取得了令人满意的结果。 (一)仪器与试剂 TH-Ⅱ型自动滴定仪(常州市无线电二厂);自动打印机,自动加液器,塑料螺旋桨搅拌.231型玻璃电极为指示电极,217型双盐桥饱和甘汞电极为参比电极(外桥液更多还原

【Abstract】 A new method for the complete analysis of chromium electroplating solution is described. Only a single acid-base titration was used. Results were calculated by a set of empirical equations,which were deduced by the author.更多还原
