A kind of chitosan-osteobiochar-based microbeads and preparation method and application thereof |
| abstract |
The present invention provides a method for preparing chitosan-Osteocarpus biochar-based microbeads. The bamboo biochar is taken out after being stirred and dipped in an alkaline solution, and subjected to the second carbonization treatment to obtain the modified Osteocarpus biochar; Mix well to obtain solution A; drop solution A into an alkaline coagulation bath for aging treatment to obtain chitosan-Osteobasidus biochar-based hydrogel beads; finally, mix the chitosan-Osteobasidus biochar-based water The gel beads are added to the cross-linking solution for cross-linking modification to obtain chitosan-ossostium biochar-based microbeads. The chitosan-osteosa biochar-based microbeads prepared by the present invention have good adsorption effects on both Cr(VI) and bisphenol A in water, and under optimal conditions, the adsorption amount of Cr(VI) is up to 321.80 mg/g, the adsorption capacity of BPA is up to 130.79mg/g. |
