电感耦合等离子体发射光谱法间接测定煤中氯

Indirect Determination of Chlorine Content in Coal by Inductively Coupled Plasma Atomic Emission Spectrometry

拟定了高压氧弹燃烧处理煤样品,电感耦合等离子体发射光谱法间接测定煤中氯含量的方法。方法经国家一级煤标准物质分析验证,结果与标准值相符,11次测定的相对标准偏差<5%。

A new method of indirect determination of chlorine content in coal by inductively coupled plasma atomic emission spectrometry with highpressure oxygen bomb method for sample pretreatment was described. The method has been verified by determination of chlorine in national standard reference coal samples. The results are in agreement with certified values with precision of < 0.5%RSD (n=11).
