Abstract
Grafting of styrene (S) onto biopolymer Sodium Alginate (NaAlg) via free-radical polymerization forming (NaAlg-g-PS), using potassium persulfate K2S2O8 (KPS) as initiator. Fourier-transform infrared spectroscopy (FT-IR) and Proton nuclear magnetic resonance (1H-NMR) characterized the formed grafted copolymer and scanning electron microscope (SEM) to show changes in the surface morphology of sodium alginate, which occurred due to the grafting process. The effect of various grafting parameters on Sodium Alginate as; Styrene and KPS concentration, the grafting temperature, and grafting time is studied. The adsorption of the grafted copolymer to both cationic dye (Malachite Green) and anionic dye (Congo Red) was investigated. In addition to the effect of the adsorption of the grafted copolymer for toxic heavy metals such as Cu2+, Cr6+, Ni2+, and Co2+. The order of the metal adsorption by grafted copolymer is Cr6+ > Cu2+ > Co2+ > Ni2+. The biological activity of the grafted copolymer was shown toward Neisseria gonorrhoeae (Gram-negative), and Bacillus subtilis (Gram-positive) using the agar diffusion method. The obtained results showed excellent improvement in the antibacterial activity of the alginate against Bacillus subtilis and Neisseria gonorrhoeae by the grafting process.Graphical abstract
