The Study on Adsorption and Separation of Ageratum Conyzoides Blue Pigment by Macroporous Resin

Abstract:

Absorption on macroporous resin was studied as a method to separate Ageratum conyzoides Flowers blue pigment in this manuscript.The optimum conditions for absorption and desorption of Ageratum conyzoides Flowers blue pigment was determined and listed as follows: D301 with the upper adsorption rate at 90.0mg/g,the stability and the little balance time was suitable for absorbing and separating Ageratum conyzoides Flowers blue pigment.The optimum condition was at the flow rate of 2.0mL/min,concentration of 0.2 mg/mL and the temperature of 20 ℃.D301 was washed with HCl of 2.0mol/L,and the washout rate achieved at 96.08%.
