摘要
采用等离子发射光谱法测定三苯基磷中铑的含量，采用直接湿法和高压硝化罐两种方法处理样品，并选择了合适的分析谱线和积分时间，方法简便，准确，快速，回收率为95％～104％，相对标准偏差〈2．0％，检出限为0．0095μg／g。
Rhodlium content in triphenylphosphine was determined with plasma emission spectrography, Sample was cured in direct wet method and high pressure nitrating pot method, Suitable analysis spectral line and integral time were selected. This method was simple, accurate and quick. The recovery rate was 95 % - 104 % The relative standard deviation was less than 2.0% and detection Limit was 0.009 5μg/mL.
