摘要
应用P350 萃取分离干扰元素 ,采用石墨炉原子吸收光谱法测定化探样品中镓 ,方法检出限为0 0 14× 10 - 6 ,相对标准偏差为 7 0 % ,回收率为 94 %～ 114%。
Ga in geochemical samples can be determined by graphite stove atomic absorption spectroscopy and through P 350 extracting and fractioning interference elements The detection limit of the method is 0 014×10 -6 ,the relative standard error is 7 0%,recovery ratio is 94%～114%
