Synthesis and Properties of adsorbent Based on carboxymethyl cellulose and tannin

摘要：

　　A bio-adsorbent was prepared by the crosslinking reaction of tannin based phenolic resin with carboxymethyl cellulose(CMC).The water absorption ratio of adsorbent decreased due to the introduction of phenolic resin based on tannin.The adsorption properties of adsorbent were improved due to the introductuion of phenolic hydroxyl group from tannin,and the maximum adsorption capacity of adsorbent for methylene blue is 1300 mg/g.The adsorption of adsorbent for methylene blue is an exothermic process.The adsorption ratio of adsorbent for methylene blue is over 98%with the adsorbent dosage of 2.5 g/L when the concentration of methylene blue in solution is lower than 2000 mg/L.The adsorbent have potential application value in the field of organic waste water treatment.
