| 摘 要： | 报道了火焰原子吸收光谱法（ＦＡＡＳ）间接测定非金属材料中氯的方法，采用ＡｇＣｌ沉淀，测定剩余Ａｇ~＋间接求出氯含量。方法的特征浓度为０．０１４ｍｇ／Ｌ（１％吸收），检出限为０．０３２ｍｇ／Ｌ（３），测定下限为０．１１ｍｇ／Ｌ，相对标准偏差（ＲＳＤ）为１．５％～１０％，样品加标准回收率在９１．４％－１０５％之间。

| Abstract: | A method for the indirect determination of chlorine in nonmetallic material by FAAS is described. After precipitation of AgCl, the surplus amount of Ag in the solution was determined for chlorine content calculation. The characteristic concentration for chlorine is 0.014 mg. L~1 (1 % absorption), while the detection limit is 0.032 mg' L~-1 (3). The relative standard deviation(n = 4) is 1.5% - 10%, and the recovery is 91.4% - 105%. |
