| titleOfInvention | Method for adsorbing heavy metal ions in water by using cellulose ester membrane |
| abstract | The invention discloses a method for adsorbing heavy metal ions in water by using a cellulose ester membrane, which comprises the steps of placing the cellulose ester membrane in an aqueous solution containing the heavy metal ions, adjusting the pH value to 2-12, and balancing for a period of time; the preparation method of the cellulose ester film comprises the following steps: the cellulose ester is obtained by esterification reaction of microcrystalline cellulose and citric anhydride, glutamic acid is introduced into the side chain of the cellulose ester through amide reaction to crosslink the cellulose ester, so that the glutamic acid crosslinked cellulose ester is obtained, and the glutamic acid crosslinked cellulose ester film can be obtained after the dispersion liquid of the glutamic acid crosslinked cellulose ester is placed in a mould to be frozen and dried. The method can adsorb heavy metal ions with low concentration in water. |
