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.
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。
