| Abstract: | This paper studies the appli cation of modified active carbon from fruit shell of chinese tallow tree in treating abolished liquid containing Cr and riching Au.Especially,after oxidizing and modifying the active carbon adsorption ability to Cr 6 increases obviously,and the ability increases according to the active carbon surfaces ratio of -COOH/-OH.The active carbon is also a kind of good Au adsorbent Modified active carbon adsorbs Au easier .It has the best adsorption quantity in such mixed acid of20%(HCl:HNO 3=3:1).With the aid of filter paper jelly,it hasthe best adsorption characteristies |
