In the current study, the effect of the immobilization on electrostatic potential, pH and the absorbance ofaqueous solutions of methyl orange that was immobilized on a modified chitosan polymer by glass wool were studied.It was found that the values of these parameters of the supported methyl orange are increased compared to unsupportedsamples. Furthermore, the electrostatic potential of the supported methyl orange is investigated in the presence of anaqueous solutions of NaCl, where showed the value of the electrostatic potential is raised With increasing ionic strengthof the sodium chloride solution and a decrease in the value of pKa to the methyl orange dye after immobilization whilethe results are inversely before immobilization methyl orange on a modified chitosan polymer by glass wool.
