树脂吸附法豆腐柴叶果胶提取液脱色的研究 (Ⅰ) D3520树脂对色素的吸附性能
STUDY ON THE DECOLORIZATION OF PECTIN LIQUID EXTRACTED FROM PREMNA MICROPHYLLA BY RESIN ADSORPTION (I) The Characters of Adsorbability of D3520 Resin to pigment
【摘要】 以大孔吸附树脂D3520对豆腐柴叶色素的吸附行为为研究对象,对色素的吸附平衡和吸附动力学进行研究,以Langmuir公式拟合25℃下的吸附等温线,结果表明:D3520树脂对色素吸附规律较好的符合Langmuir吸附等温式。
【Abstract】 Adsorption equilibrium and kinetics of premna microphylla pigment was studied for D3520 macroporous resin adsorbent. The adsorption equilibrium could be described with the Langmuir isotherms equation, the results showed that the adsorption accords with Langmuir adsorption isotherm。
