摘要
采用大孔吸附树脂分别对以水和乙醇为溶剂制得的板栗壳棕色素Ⅰ和色素Ⅱ进行精制，确定了色素Ⅰ以Ｄ４０２０，色素Ⅱ以ＮＫＡ－９为吸附剂，并对精制效果作了评价。本文为吸附树脂在色素中的应用提供一定的科学依据。
Polymer adsorbents were used to refine the brown pigment Ⅰ and Ⅱ which extracted from chestnut shells by water and ethanol respectively.The adsorbent was selected:pigment Ⅰ by D4020,Ⅱ by NKA 9.The effection of purification was evaluated.The paper offered basis for the application of polymer adsorbent in pigment refining.
