Chitosan/ sodium alginate scaffold removes Fe from underground water and combat multidrug-resistant bacteria

Underground water is an important source of drinking water worldwide. The occurrence of iron in water can cause staining, as well as unpleasant appearances and tastes. Therefore, in our study, we have formulated a 3D scaffold based on chitosan/ sodium alginate/ox. Cellulose/GO (Cs/SA/Ox. Cell/GO) has been prepared. Cellulose has been oxidized by TEMPO to make cellulose more reactive. Then ox. cellulose has been mixed with chitosan/ sodium alginate solution in the presence of different ratios of GO. The scaffolds have been investigated via FTIR, XRD, and SEM techniques. The prepared scaffold has been used for Fe+2 removal from underground water at different times, different pHs, and different dosages. The Antimicrobial activity of the prepared scaffold has been studied. Five pathogenic microorganisms were isolated from samples and identified by biochemical tests as Pseudomonas aeroginosa, Neisseria sp., Klebsiella sp., Plesiomonas shigelloides, and Salmonella sp. Composite 3 showed antimicrobial activity against a number of pathogenic microorganisms. The inhibition efficiency ranged between 12-25 mm. Thus, the prepared scaffold is considered a promising material for iron removal, besides having good antimicrobial activity.
