Chitosan-Based Hydrogels,adable, furthermore can be used into different shapes, such as beads, hydrogels, powders, films and membranes. Chitosan hydrogels may be formed by different mechanisms, as physical association or chemically cross-linked, thus can vary its geometries, formulations and shapes. Usually, hydrogels are p唤起 发表于 2025-3-28 23:21:54

Chitosan for Direct Bioflocculation Processes,olves metal salts as coagulants and synthetic organic polymers as flocculants. Although those chemicals are cheap, efficient, available and easy to use, they have drawbacks such water pollution by metals, and production of large amounts of toxic sludges. Therefore, safer biocoagulants and biofloccul
