3.In this work was conducted the comparative study of hydrolytic polyacrylamide (HPAM), polaluminum chloride(PAC), polyferric sulfate(PES) and aluminum for removing acidic dyes, such as Polar Brilliant Red IOB, Fast NewTral Yellow G and Turquoise Blue 5GM from water. The optimal conditions and decolorization rate for the four coagulants to treat the acidic dyes in water were investigated. It was found that PFS was the best coagulant to remove the three kinds of acids dyes from water.
5.8 Kinds of food additives, tartrazine, amaranth, benzoic acid, saccharine, sorbic acid, ponceau 4R, sunset yellow FCF and brilliant blue FCF in fruit juices were simultaneously determined by reversed phase-high performance liquid chromatography(RP-HPLC) on a Hypersil BDS C18 column(5 μm, 250 mm×4 mm i.d.)
