本文介绍了用碘量法测定制革下脚料的铬含量。研究了方法的准确度和精密度 ,比较了原子吸收分光光度法测定的数据与本法的差别 ,并排除了制革下脚料中微量铁对测定的干扰。 This paper describes the determination of chromium content of tannery waste by iodometry. The accuracy and precision of the method were studied. The differences between the data determined by atomic absorption spectrophotometry and the present method were compared, and the determination of trace iron in tannery scraps was excluded.
