Euryale ferox Salisb. is an important plant resource and valuable tonic in traditional Chinese medicine. The seed of Euryale ferox Salisb. is rich in starch. There are few reports of modification and functional properties of Euryale ferox starch. In present study, the Euryale ferox starch was extracted, carboxymethyl etherified starches were synthesized, the starch-based hydrogels were prepared, and adsorptive properties were investigated. The results of investigation showed that carboxymethyl etherified Euryale ferox starch-based adsorbent has the potential for methylene blue removal. Therefore, Euryale ferox starch has an appealing application prospect in adsorption for scavenging dyes from real complex waste liquid.
