    Adsorption on polysaccharide derivatives can be a low-cost procedure of choice in water decontamination for extraction and separation of compounds, and a useful tool for protecting the environment. In current study, polysaccharides-silica composites were synthesized by sol-gel method, physical and chemical adsorption of chitosan and carrageenan by silica surface. Obtained adsorbents were applied to adsorption of highly toxic compounds: cationic and anionic dyes, herbicides and heavy metals.
