Adsorption of Heavy Metals by Nanocellulose Modified by Ammonia Triacetic Acid
The use of the waste naked oats straw in Wuchuan County,Inner Mongolia Autonomous re-gion to prepare nano modified naked oats straw cellulose,respectively from the adsorbent dosage,adsorp-tion time and solution pH value of the copper ion adsorption performance of the comparative study,When the dosage of HCl-NTA-NOSC is about 0.1g,the adsorption rate is the highest,which can reach 30%to 35%.The optimum adsorption time was 60 minutes,and the adsorption capacity reached the peak at 60 minutes.The adsorption effect is best when the pH value of solution is about 5.
