文献[1]报道了二安替比林苯乙烯甲烷测定部分变价元素有较高灵敏度。章道昆指出有锰(Ⅱ)存在时钒(Ⅴ)、铈(Ⅳ)灵敏度显著增加。本研究同样发现有锰(Ⅱ)存在时该试剂使铬(Ⅵ)的摩尔吸光系数由2.5×10~4l·mol~(-1)·cm~(-1)增至1.5×10~5l·mol~(-1)·cm~(-1),为微量铬(Ⅵ)的测定提供了迄今为止文献尚未报道的新方法。 Literature [1] reported that diantipyryl styrene methano methane has some sensitivity to the variable-price element. Zhang Daokun pointed out that the sensitivity of vanadium (Ⅴ) and cerium (Ⅳ) increased remarkably when manganese (Ⅱ) was present. In the present study, it was also found that the molar extinction coefficient of chromium (Ⅵ) increased from 2.5 × 10 4 l · mol -1 · cm -1 to 1.5 × 10 5 L ·· -1 in the presence of manganese (Ⅱ) mol ~ (-1) · cm ~ (-1), providing a new method for the determination of trace chromium (Ⅵ) which has not been reported in literature so far.
