An effective and recyclable decolorization method for polysaccharides from Miquel by magnetic chitosan microspheres.

The purpose of this research was to develop an efficient and non-destructive method for decolorizing of polysaccharides extracted from Miquel by magnetic chitosan microspheres (MCM). The optimum decolorization parameters were achieved by response surface methodology as follows: the MCM amount was 8.0%, the adsorption temperature was 48 °C, the adsorption time was 82 min and the pH was 7.
