Preparation and characterization of chitosan-curdlan composite magnetized by zinc ferrite for efficient adsorption of tetracycline antibiotics in water.

Tetracycline (TC) antibiotic-related water pollution directly threatens human health and ecosystems. Here, a zinc ferrite/chitosan-curdlan (ZNF/CHT-CRD) magnetic composite was prepared via a co-precipitation method to be used as a novel, green adsorbent for TC removal from water. Benefiting from a multitude of functional groups, CRD was first crosslinked with CHT and then magnetized with ZNF to provide an easy separation from the solution with an external magnetic force.

Magnetized inulin by FeO as a bio-nano adsorbent for treating water contaminated with methyl orange and crystal violet dyes.

Current work focuses on fabricating a new bio-nano adsorbent of FeO@inulin nanocomposite via an in-situ co-precipitation procedure to adsorb methyl orange (MO) and crystal violet (CV) dyes from aqueous solutions. Different physical characterization analyses verified the successful fabrication of the magnetic nanocomposite. The adsorbent performance in dye removal was evaluated by varying initial dye concentration, adsorbent dosage, pH and temperature in 5110 mg/L, 0.
