The influences of factors such as pH value,contact time,adding dosage of adsorbent and Cr6+ initial concentration on the adsorption results were discussed through the adsorption experiment on shaddock peel modified by isopropanol.The results indicated that modified shaddock peel had good adsorption to Cr6+.The optimal conditions of absorption were as follows: the value of pH was 5,the initial concentration of Cr6+ was 35μg/mL,the reaction time was 45 min,and the dosage of absorbent was 6g/L,the adsorption r...
