采用电解法分离铜后,电感耦合等离子体-原子发射光谱法直接测定了铜-银-磷钎料中磷的含量。实验表明,在1.0moI·L~(-1)硝酸电解液中可以使铜基本电离完全,对磷的测定不产生干扰。在最佳的测定条件下,该法用于铜-银-磷钎料中磷的测定,回收率在98.3%—102.4%之间,相对标准偏差2.28%。
After copper was separated by electrolysis, the content of phosphorus in the copper-silver-phosphorus solder was directly determined by inductively coupled plasma-atomic emission spectrometry. Experiments show that in 1.0moI · L -1 nitric acid electrolyte can make the basic copper ionization, the determination of phosphorus does not interfere. Under the optimum conditions, the method was applied to the determination of phosphorus in copper-silver-phosphorus solder with the recovery of 98.3% -102.4% and the relative standard deviation of 2.28%.
