摘要
建立了火焰原子吸收光谱法测定不同价态铬含量的方法。该方法的检出限为0.029mg·L-1;相对标准偏差为0.54%;平均加标回收率为99.3%;利用此分析方法测定了废水中不同价态铬的含量,结果令人满意。
A method for the determination of chromium amount in different valence states in the waste water by flame atomic absorption spectrometry was established .The detection limit was found to be 0.029mg·L-1. The relative standard deviation was 0.54%; The average recoveries of standard addition was 99.3%. The proposed method has been applied to the determination of chromium amount in different valence states in the waste water from factories with satisfactory results.
