WebObjective The present investigation entailed determination of effect of diverse cross-linking agents on Losartan Potassium loaded chitosan microspheres. The emulsion cross-linking method was employed to formulate the microspheres with an endeavour to achieve maximum sustained effect. WebHerein, we report the ultrasound wave-induced synthesis of crosslinked chitosan hydrogels (CAAT and CAAG) using terephthalaldehyde/glutaraldehyde as crosslinking agents and their comparison for the removal of synthetic anionic dyes from aqueous media. Synthesized hydrogels were characterized via spectral, thermal, X-ray crystallographic ... WebApr 11, 2024 · A copper ion imprinted chitosan flocculant (Cu 2+ @CTS) was synthesized by the molecular imprinting technique to improve the flocculation selectivity of chitosan to heavy metal ions. The effects of the amount of crosslinking agent, crosslinking time, temperature on the properties of the material were systematically investigated. ind vs south africa 4th t20 highlights
