A new class of injectable, biocompatible and biodegradable hydrogel is reported. This hydrogel is derived from N-succinyl chitosan (SCS) mixed with water-soluble dialdehyde starch (DAS) without using a conventional chemical crosslinker. The hybrid hydrogel is formed owing to the Schiff's base reaction between amine groups of SCS and dialdehyde groups of DAS to form -CH 000000000000 000000000000...
A novel kind of hydrochar adsorbent, modified by CuO-ZnO and derived from chitosan or starch, was synthesized for H2S adsorption. The prepared adsorbent characterized BET, XRD, EDX, SEM, XPS. results showed that the contained many amino groups as functional groups, nanometer metal oxide particles had good dispersion on surface hydrochar. maximum sulfur capacity reached 28.06 mg/g-adsorbent unde...
Safe biodegradable “green” alternatives with minimal environmental and health risks have received widespread research interest. Thirty different kinds of bio-based flocculants (modified starches, modified celluloses, native chitosan, and lignin-based flocculant) were pre-tested using a simple jar test for the examination of the applicability of new organic flocculants in papermaking and in cond...
