Activated Carbon Decolorization Process of Carnosic Acid
Study the optimal process for decolorization of camosic acid using activated carbon.Using decolorization rate and camosic acid yield as evaluation indicators,the effects of activated carbon addition,decolorization temperature,decolorization pH and decolorization time on decolorization rate and camosic acid yield were studied through single factor experiment and orthogonal experiment.The optimal decolorization process for camosic acid was addition of 0.2% activated carbon,decolorization temperature of 50 ℃,decolorization pH of 3.0,and decolorization time of 15 minutes.Under the condition,the decolorization rate was 25.02% ,and the camosic acid yield was 94.62% .The use of activated carbon for decolorization of camosic acid is feasible,and under certain conditions,high decolorization rate and yield of camosic acid can be achieved.
