| Abstract: | The adsorption and desorption performance of nine macroporus adsorbent resin for separation pigments from Rhodomyrtus tomentosa,a suitable resin was chosen and the adsorption and desorption condition were optimized.The results showed that X-5 had higher capacity at pH3.0,which dynamic adsorption rate was 94.36%,and adsorption capacity was 70.12mg/mL resin.The pigment produced by this method was dark purple power,and its color value was 18.45 which was nine times of before. |
