Introduction | transparent red EG is a pyrene ketone solvent dye. The solvent Orange 60, transparent red EG and Solvent Red 179 are the most valuable pyrene ketone Solvent dyes. Transparent Red EG is mainly used for polyester and polyester fiber pulp coloring. |
determination of impurities | transparent red EG is mainly used for coloring polyester and polyester fiber puree, and its synthetic raw materials may contain hexachlorobenzene, the purpose of determining the content of hexachlorobenzene is to achieve the green environmental protection index of the solvent dye and its application field, and to ensure the counter restriction of the EU green barrier. Hexachlorobenzene (C6Cl6, HCB) is a global environmental pollutant, which has been listed as one of environmental endocrine disruptors (environmental endocrine disruptors, abbreviated as eds), and has reproductive toxicity and difficult decomposition. Its lowest observed effect level was documented to be 0.25-2.0 mg/kg/day and HCB has been found to play a role in human breast cancer. Therefore, more and more attention has been paid to the effect of HCB residues on human health and environment. Liao Xiao et al. used solvent extraction gas chromatography-mass spectrometry/selective ion scanning to determine the content of hexachlorobenzene in solvent dye transparent red EG. The relative standard deviation of this method was 3.3%, and the recovery rate was high. The detection limit reached 0.05 mg/kg, and a large number of samples were analyzed. |
