To elevate the red pigment from Suaeda salsa color value, the characteristics of static adsorption and desorption of six kinds of macroporous resins (X-5, HPD300, D101, HPD400, NKA-9, and AB-8) to red pigmentfrom S. salsa were investigated. The purification processes conditions of the best macroporous resin for red pigmentfrom S. salsa were also studied. The result indicated that X-5 resin was suitable for purifying red pigment from S.salsa. The appropriate dynamic conditions were liquid concentration 1 mg/mL, pH value 6, and flow rate 5 BV/h. Andusing 60% ethanol as effluent at 5 BV/h in speed, after purification, the color value of purified pigment was 6.14times higher than the original one. |
