Complex Decolorizer of Active Carbon and Attapulgite for the Decoloration of Lentinan Extract

Abstract:

The complex decolorizer of active carbon and attapulgite was synthesized for the decoloration of Lentinan extract. The effects of decolorizer dosage, temperature and pH were investigated through single factor experiments. The experimental results show that the decoloration rate with the complex decolorizer was close to that with the active carbon, while the loss rate of polysaccharide was significantly lower than that with the active carbon. The optimum decoloration conditions were decolorizer dosage 2 wt%, temperature 50 oC and pH 6.0. Under these optimum decoloration conditions, the decoloration rate and the polysaccharide loss rate were 87.2% and 12.6%, respectively.
