The decolorization of five kinds of azo dyes-azo blue, eriochrome black T, arsenazo III, acid chrome blue K and methyl orange,and one kind of quinoid dye-alizarine red with potassium ferrate are studied. 研究了高铁酸钾对偶氮蓝、铬黑 T、偶氮胂 III、酸性铬蓝 K和甲基橙 5种偶氮染料及一种醌类染料茜素红的脱色作用 .
after treatment with chrome salt [机] 铬盐处理
The analytical errors caused by the interference of the complexation reagent acid chrome blue K can be reduced by taking the reagent itself as a component of the system to be analyzed. 对所测的光谱进行傅里叶变换滤波,求混合体系光谱与显色剂光谱的比光谱,再对波长求导,然后对剩下的两组分中的一组分的光谱进行比值求导;
