用氢氧化钾和硝酸钾熔融法分解硅酸盐样品

DECOMPOSITION OF SILICATE SAMPLE BY FUSION WITH POTASSIUM HYDROXIDE AND POTASSIUM NITRATE

介绍了用ＫＯＨ和ＫＮＯ＿３熔融法分解硅酸盐样品的方法。分解后的试样溶液可用于痕量稀土核素的分离纯化。实验结果表明，用本方法处理硅酸盐样品，分解温度低于３００℃，样品量可达１０ｇ。

The decomposition method of silicate sample by fusion with KOH and KNO_3 recounted.Thedecomposed sample can be used to separate and purify the rare earth nuclides. The advantage ofthis method is that it can decompose larger amount of sample under lower decompositiontemperature.
