ICP-AES测定载金树脂物料中的金

Determination of Au in Gold loaded resin material by ICP-AES

试样经高温灰化后,用王水溶解残渣后定容,采用ICP-AES测定"载金树脂物料"中的金含量。实验结果表明测定相对标准偏差小于3%,回收率在97.1%—107%之间,方法简便,快速,可靠。

The samples were treated high-temperature ashing, dissolve the residue with aqua regia, and the amount of Au in ＂gold loaded resin material＂ were determined by ICP-AES. Experimental results show that the relative standard deviation less than 3%, Recoveries between 97. 1% and 107% ,the method is simple,rapid and reliable.
