Preparation and Characterization of Phthaloyl Chitosan as a Novel Purifying Agent for Deltamethrin

To develop a bio adsorbent with enhanced adsorption properties to remove deltamethrin pesticide from aqueous solutions, a modified chitosan material was successfully obtained by modifying chitosan with phthalic anhydride. The obtained products were characterized with the necessary chemical and spectroscopic techniques and were studied as an adsorbent for deltamethrin removal from aqueous solutions. To determine the optimum conditions of this reaction, pH, the initial dose of deltamethrin and the amount of modified chitosan to be added were mentioned. The decrease in the concentration of the previously prepared sample due to the adsorption reaction was studied with the aid of gas chromatography.
