石墨炉原子吸收光谱(GFAAS)法测定石英玻璃中硼的研究

Study on Determination of B in Silex Glass by GFAAS

试样经氢氟酸分解,通过加入化学改进剂和多次注射浓缩样品及低温、长时间灰化的方法,在硝酸介质中用石墨炉原子吸收光谱法(GFAAS)测定石英玻璃中硼的含量。该方法解决了GFAAS法分析石英玻璃中硼灵敏度低和准确度低的问题。

The sample was decomposed by HF. By means of adding chemical modifier, multiple injections of condensed solution of sample, and cineration at low temperature for long time in a medium containing HNO3, the content of B in silex glass was determined by GFAAS. This method solves the problem of low sensitivity and low accuracy when B in silex glass is determined by GFAAS. 
