砷化氢分离砷钼蓝分光光度法测定铁矿石中的砷

Arsenic Molybdenum Blue arsine Spectrophotometric Determination of iron ore separation of arsenic

介绍了简易可行的实验装置,采用砷化氢分离[1],碘吸收溶液吸收,砷钼蓝分光光度法测定铁矿石中的砷含量,并考虑了砷化氢发生分离的最佳酸度,显色反应的适宜条件,以及共存离子的干扰,提出了相关的实验条件和分析方法,通过该方法分析铁矿石中的砷含量,其方法简单,结果稳定。

This paper introduces a simple and feasible experimental device used arsine separation of iodine absorption. Speotro- photometric Determination of Arsenic Molybdenum Blue arsenic content in the iron ore, and considered the best separation occurred arsine acidity, color reaction d the appropriate conditions and intedering ions, the experimental conditions and the relerant analytical method through the analysis of arsenic content in iron ore, the method is simple, the results are stable.
