The dynamic adsorption decolorization technology of alkyl poly- glycosides surfactant with weak basic anion-exchange resins was studied. The decolorization products of PH is no evident change, it also has good stability, high transparency and clarification, no flocculent deposition; no bad smell; inorganic salt is low quantity percent, operation method is brief and rapid, which macro-porous weakly basic anion exchange resins is easy regeneration. Absorbance is 0.058 at 470nm wavelength. At Strengthening Experimental, the absorbance is 0.051 within 72h.Through measurement technique of IR and gas chromatography proved that the structure of alkyl poly-glycosides surfactant remain unchanged.
