摘要
采用三氯化铁一重铬酸钾容量法测定钒渣中的金属铁的含量,消除了汞害,简化了装置,提高了分析速度,适于工业分析。同时由于随同试样做空白试验,消除了干扰,提高了分析精度。
FeCl_3 - K_2 Cr_2O_7 volumetric analysis is used for the determination of metal Ferrum in vanadium residue, which abstains from the use of mercury, simplifies device, improves the speed of analysis. This method is adapted to the industrial analysis. In the meantime the blank test eliminates inference and improves the precision of analysis.
