- W2376740516 abstract "A new method for gravimetry of high content Ru in difficultly dissolved Ru-B solder using NaBH 4-H 2 reduction was established.The conditions were studied,systematically.The acerbity decomposition method of glass-envelop-tube for sample was compared with alkali fusing method,and at the same time,the gravimetry of NaBH 4-H 2 reduction for Ru was compared with distillation-thiourea color spectrophotometry.The results showed that the acerbity decomposition method of glass-envelop-tube was time-comsuming and its operation was much complex than the alkali fusing method,but the system of gravimetry was simple.The gravimetry of NaBH 4-H 2 reduction was time-comsuming than the distillation-thiourea color spectrophotometry,but because of high determining concentration of Ru,its relative error was less.For the determination of 50 mg～100 mg of Ru,relative error was-0.24%～+0.25%.The proposed method has high accuracy,good selectivity and better applicability,and it has been applied to determine Ru in Ru-B solder with satisfactory results." @default.
