摘　　要：使用石墨炉原子吸收分光光度法测定工业高锰酸钾中铬的含量,通过不同的基体改进剂对实验结果的影响。简单的研究了磷酸二氢铵、硝酸镁、硝酸钯3种基体改进剂在测定高锰酸钾中铬含量的运用,结果表明硝酸镁作为基体改进剂时测定检测的精密度和回收率相对最好,实验稳定性更好。The researchers measured the level of chromium in potassium permanganate for industrial use by graphite furnace atomic absorption spectrometry and analyzed the impact of different matrix modifer on the results. The research shows that using magnesium nitrate results in a better outcome in precision, recovery rate, and consistency when compared with using ammonium dihydrogen phosphate and palladium nitrate.
