一种吸附蛋白酶解液中重金属铬的工艺
摘要：
本发明公开了一种吸附蛋白酶解液中重金属铬的工艺，其主要由蛋白酶解液中铬浓度的调节、pH调节、复合吸附剂配制、吸附和分离等步骤组成。本发明所采用的吸附剂为聚乙烯亚胺改性羧基化纳晶纤维素与海泡石复合吸附剂，具有吸附重金属效果好，几乎没有副作用的优点；吸附蛋白酶解液中重金属铬的工艺简单易行，而且所采用的吸附剂易于除去，不会产生其他污染。
摘要（英）：

The invention discloses a technology for adsorption of heavy metal chromium in a proteolysis liquid. The technology mainly comprises proteolysis liquid chromium concentration adjustment, pH adjustment, composite adsorbent preparation, and adsorption and separation. The adsorbent is a polyethyleneimine-modified carboxylic nanocrystal cellulose-sepiolite composite adsorbent and has the advantages of good heavy metal adsorption effects and little side effect. The technology has simple and easy processes. The adopted adsorbent can be removed easily and does not cause other pollution.
