The hybrid chitosan-derived mesoporous spongy carbon (HCMSC) bio-adsorbent showed efficient and highly selective removal of Fe3+ toxins (>99%) from real water samples, making it a promising method for treating heavy metal ions in practical applications.
Herein, a hybrid chitosan-derived mesoporous spongy carbon (HCMSC) bio-adsorbent was prepared and used for efficient and extremely selective removal of Fe3+ toxins (>99%) from real water samples to generate Fe-free water for human usage. HCMSC bio-adsorbent was fabricated through direct grafting of 4-(2-(3-Methyl-5-oxo1-tosyl-1H-pyrazol-4(5H)-ylidene) hydrazinyl)-N-(pyrimidin-2-yl) benzenesulfonamide (PHBS) onto the chitosan-derived mesoporous spongy carbon (CMSC). The finding data demonstrated superior adsorption efficiency (>99%) and capacity (165 mg/g) of used HCMSC bio-captors toward Fe3+ ions at pH 4.5. The offered outcomes suggested that the batch-adsorption model kept their functionality to adsorb Fe3+ toxins even after numerous reuse periods effectively using 0.2 mol/L of HCl as eluent agent. Furthermore, the real applicability of HCMSC bio-adsorbent was achieved to remove Fe3+ ions from real water samples under optimum removal conditions.
