Abstract

The raw material for Fast Green FCF was tested for preparation of the "Fast Green FCF Standard (C.I. 42053)". Analytical data obtained were as follows: paper chromatography, only one spot is observed; arsenic content, 0.38 microgram/g; chloride content, 0.11%; sulfate content, 3.30%; heavy metals, lead, 8.0 micrograms/g, manganese, 28.1 micrograms/g, and chromium, 1.6 micrograms/g; infrared spectra, 1575 cm-1, 1169 cm-1, and 1033 cm-1; loss on drying, 2.39%; assay, 93.0% by the titanium trichloride titration. Based on the above results, the raw material was authorized as the Dye Standard of National Institute of Health Sciences.

【国家卫生科学研究院染料标准“快速绿色FCF标准”研究】。
对Fast Green FCF原料进行了测试,以制备“Fast Green FCF标准(C.I. 42053)”。得到的分析数据如下:纸层析,只观察到一个斑点;砷含量0.38微克/克;氯化物含量:0.11%;硫酸盐含量:3.30%;重金属:铅8.0微克/克、锰28.1微克/克、铬1.6微克/克;红外光谱,1575 cm-1, 1169 cm-1和1033 cm-1;干燥损失2.39%;测定,93.0%为三氯化钛滴定法。根据上述结果,该原料被批准为国家卫生科学研究院染料标准。
