Description
In the current study, Phosphorization of Alginate was done via activation of Alginate with Epichlorohydrin then introduces Orthophosphoric as a source of phosphonic groups. Four different molar ratios of Phosphorization were prepared. Phosphorus content was determined using elemental analysis by EDX unit. Physical characterization including moisture content, and ion exchange capacity was examined and confirm phosphorylation step. The structure of the prepared new alginate derivative was characterized using Electronic spectrum (UV-Vis spectrum), Fourier transform infrared FT-IR, Raman Spectroscopy, thermal gravimetric analysis (TGA), Differential scanning calorimetric (DSC) and Scan electron Microscope (SEM).
