This is a chrome green colour stain which develops especially well in glazes containing little or no zinc or magnesium. Transparent glazes favour the development of the colour. 铬绿色料在少含或不含锌、镁的釉中呈色特别好。透明釉有利于发色效果。
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 .
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;
