摘要: 研究了吸附和分离洛神葵色素的方法和条件,粘土-SA01对洛神葵色素具有较好的吸附能力,温度、酸度等因素对吸附能力有一定影响。温度升高吸附较快,但温度升高到30℃以上时随着时间的延长色素的稳定性受影响。粘土-SA01对洛神葵色素的吸附能力在pH=1左右时比其它酸度条件下更强。乙醇浓度对粘土-SA01上色素的解脱效果有影响,乙醇浓度为40%时解吸效果最佳。

Abstract: The article studied condition and methods of adsorbing and refining Rose Eggplant pigment was studied. In severaltypes of Activated White Clay-SA01 tested, the adsorbing ability of Activated White Clay-SA01 is best. The results show thattemperature, acidity etc, can influence the adsorbing ability. At pH=1 Activated Clay-SA01 has the greatest absorbing ability. Theconcentration of alcohol can influence the desertion. When the concentration of alcohol is 40% the desertion is most effective.

Key words: rose eggplant pigment, clay- SA01, absorption, desertion, separation
