Facile Synthesis of Cross-Linked Chitosan-Genipin/Algae Composite Adsorbent for Cationic Methyl Violet Dye Removal: Robust Modeling of Adsorption Using the Box-Behnken Design
A biopolymer matrix of chitosan (CTS) and algae (AGA) was chemically modified with a natural genipin (GEN) cross-linker agent via hydrothermal process. The resulting green adsorbent (CTS-GEN/AGA) was evaluated for removal of the cationic dye (methyl violet, MV) from aqueous media. The optimization o...

A biopolymer matrix of chitosan (CTS) and algae (AGA) was chemically modified with a natural genipin (GEN) cross-linker agent via hydrothermal process.
