【摘要】 以矿物油加脂剂和阳离子型加脂剂为试验材料,测定了难降解加脂剂对酸性品红染料脱色度的影响,探讨了阳离子型加脂剂抑制偶氮染料生物脱色的机理。结果表明:矿物油加脂剂对染料的脱色活性无影响,而阳离子型加脂剂则由于其自身的生物毒性,对染料的生物脱色具有一定影响,但与磷酸酯盐型加脂剂相比,抑制作用较小。更多还原

【Abstract】 The influence of two fatliquor on the decolorization activity of the acid fuchsin dye was investigated, namely the mineral-oil fatliquor and cationic fatliquor. The inhibition mechanism of the cationic fatliquor on the decolorization was studied. The results show that the mineral-oil fatliquor has no effect on the decolorization of dyes, and the cationic fatliquor whith has the biological toxicity resultes in the inhibition on the decolorization. But the inhibition of the cationic fatliquor is smaller than that of the phosphoric fatliquor.更多还原
