Synthesis of novel antibacterial grafted sodium alginate copolymer-based adsorbent for wastewater treatment

Abstract Grafting of styrene (S) onto biopolymer Sodium Alginate (NaAlg) via free-radical polymerization forming (NaAlg-g-PS), using potassium persulfate K 2 S O 8 (KPS) as initiator. Fourier-transform infrared spectroscopy (FT-IR) and Proton nuclear magnetic resonance ( 1 H-NMR) characterized the formed grafted copolymer scanning electron microscope (SEM) to show changes in surface morphology sodium alginate, which occurred due grafting process. The effect various parameters on as; Styrene KPS concentration, temperature, time is studied. adsorption both cationic dye (Malachite Green) anionic (Congo Red) was investigated. In addition for toxic heavy metals such Cu 2+ , Cr 6+ Ni Co . order metal by > biological activity shown toward Neisseria gonorrhoeae (Gram-negative), Bacillus subtilis (Gram-positive) agar diffusion method. obtained results showed excellent improvement antibacterial alginate against Graphical abstract
