摘要
本文研究了氢化物发生-火焰分子发射光谱测定地质样品中As的方法,提出并采用了一种新型分子发射炉(腔)——长缝式石英炉。该方法具有设备简单、操作方便、干扰少、线性动态范围宽等特点。方法检出限为0.02μg/ml,对0.5μg/ml As的样品测定,其RSD(n=10)为1.5％。用GSS及MGD系列部分标样验证了方法的可靠性。
A hydride generation-flame molecular emission spectrometric method for the determination of As in geological samples is reported and a new emission device-a slotted quartz burner is suggested. The method is free from
interference and the detection limit is 0.02μg/ml. The results of analyses of standard geological sample are in good agreement with the certified values.
