건립료사금중15충희토원소적전감우합등리자체질보측정방법.고찰료기체 Au 적보선간우급기체효응,채용 In 내표보상기체대대측신호적억제작용.의기검측한위0.0009~0.0029μg/L,가입표준물질적회수솔위98%~106.7%,분석결과적상대표준편차(RSD)위0.33%~1.79%.해방법간단、쾌속、령민、준학.
A determination method of 15 rare earth elements in gold placer by inductively coupled plasma mass spectrometry was established.The effects of spectral interference and matrix effect of the substrate Au were investigated and the inhibition matrix did to the measured signal was compensated using In as internal standard .The detection limit is 0.000 9 -0.002 9 μg/L,the recovery was 98 % -106.7 % by standard substance addition and the relative stand -ard deviation(RSD)of the analysis is 0.33 % to 1.79 %.The method is simple,quick,sensitive and accurate.
