采用空气-乙炔火焰和四丁基氯化铵(TBAC)作增敏剂进行了铝的测定,考察了各种含氨化合物的增敏作用及各种酸对它的影响,通过标准加入法消除了基体共存元素的干扰。建立的方法可满意地进行工业硅中x‰～x％铝的测定。
The determination of aluminum with air-acetylene flame and tetrabutylammonium chloride (TBAC) as sensitizer was carried out to investigate the sensitization effect of various ammonia-containing compounds and the effects of various acids on it, which were eliminated by standard addition The matrix coexistence of elements of interference. The established method can satisfactorily measure x ‰ ~ x% aluminum in industrial silicon.
