Chitosan–humic acid composite cryogels for heavy metal adsorption: insights from single and binary aqueous systems

Key Points

• Significant heavy metal adsorption is observed with the composite cryogels in aqueous systems, improving water quality.
• Chitosan-humic acid cryogels demonstrate superior performance in single and binary systems for adsorbing pollutants.
• The analysis evaluates heavy metal adsorption across different concentrations, focusing on efficiency and capacity.
• These findings may enable new methods for water treatment, addressing issues of toxicity and bioaccumulation.
