| titleOfInvention | Preparation of cellulose-based adsorbents containing the quaternary ammonium functional groups and their recycling methods |
| abstract | The present invention relates to a cellulose-based adsorbent having a cationic functional group and a regeneration method thereof, and more particularly, to a cellulose-based functional group selected from epoxide, isocyanate, isothiocyanate, acyl halo, halogen, and anhydride under alkali catalyst. By cross-linking with a compound containing two or more compounds and reacting with a quaternary ammonium compound having a cationic functional group to prepare a cationic cellulose adsorbent, the adsorption rate and the amount of adsorption are very large compared to the adsorbents of conventional dyes, thereby greatly improving the wastewater treatment process. The present invention relates to a cellulose-based adsorbent having a cationic functional group which is environmentally friendly and economical since it can be easily recycled and has a low burden on waste disposal. |
