Abstract Water-borne infections are considered as one of the major risky concerns regarding sanitary state water bodies dedicated to drinking supply. Therefore, employment environmentally benign materials in water/wastewater treatment is an indispensable aspect solve crisis problem eco-friendly and economic manner. This study describes synthesis, characterization, disinfection potency different formulas gelatin-based Gum Arabic composites, for first time. SEM, XRD, FTIR, ζ- potential, swelling tests were used assess their physicochemical properties, which revealed enhanced compatibility miscibility with increasing concentration. The formula GEL/50%GA showed more homogenously distributed pores visualized by SEM noticeable shifts characteristic FTIR-band negatively charged surface, reflecting considerable stability indicated ζ-potential. Besides, it also had superior hydrophilic swellability levels. Interestingly, results antimicrobial activity susceptibility broad-spectrum microbes against examined especially elevating concentration incorporated composite.
