Abstract
A novel grafting polymer was synthesized via the grafting of Diphenylamine (DPA) onto Sodium alginate (Na.Alg) for several applications, as the new polymer (adsorbent) for heavy metals from aqueous solutions, hydrogen generation, and antimicrobial agent. Optimization of Sodium alginate grafted by Diphenylamine (Na.Alg-g-DPA) was addressed in the current study by several parameters including; initiator and monomer concentrations, the contact time of polymerization, as well as polymerization temperature. Besides, the structural and chemical characteristics of Na.Alg-g-DPA were explored using different modalities later. The results showed that Sodium alginate grafted by Diphenylamine (Na.Alg-g-DPA) is suitable for adsorbent removal of Co2+ ions. The parameters for the adsorption of Co (II) ions by Na.Alg-g-DPA were studding these parameters such as the effect of time, temperature, PH, and concentration of Co+2. Also, we were Studying the size of molecules of the polymer by different analysis such as FTIR, XRD, H-NMR, TEM, SEM, surface area which to know the size of the atom, the surface area, and the chemical and physical properties.
Also, incorporate the polymer with active material which affects different fields such as silver nanoparticles and its applications on Antimicrobial activity and treatment of Fungi and harmful viruses. To improve its properties as an Antimicrobial agent the new material structural and chemical were characterized by FTIR, XRD, SEM, and antimicrobial analysis against different species of fungi and bacteria such as Fungi (Aspergillus fumigatus ATCC 13073 and Candida albicans ATCC 10231), Gram-positive strains (Streptococcus pneumoniae ATCC 6303 and Staphylococcus aureus ATCC 29213), and Gram-negative strains (Pseudomonas aeruginosa ATCC 27853 and Escherichia coli ATCC 25922). All results make sure it`s a benefit for killing the hazardous microorganisms and for the environmental pollution also.
