  1. 用于硝酸铬及氯化铬中痕量铬(Ⅵ)的测定,得到了满意的结果。

    The method has been applied to the determination of trace amount of Cr (ⅵ) in chromic nitrate and chromic chloride . The results obtained are satisfactory .

  2. 经催化剂性能评价,发现当硝酸铬与助剂摩尔比为1:1.25,锻烧温度在500~550℃之间,所制得的催化剂活性较高。

    The results of performance evaluation showed that the catalyst had the highest catalytic activity when the ratio of chromic nitrate to promoter was 1: 1.25 and the calcination temperature was 500 ~ 550 ℃ .
