In this study, sericin / chitosan particles were prepared by electrostatic spraying method. The effects of 3% chitosan on the environment were investigated. The results showed that 3% chitosan had a voltage of 20kV, working distance 10 cm, and the flow rate was 5 ml / min. The mixture was mixed with 8% sericin to form microparticles. The average diameter of the particles was 642.53 ± 1.962nm. As a result of the gravitational interaction between the polysaccharide and the protein, the results showed that when the addition of sericin particles into the dye, the adsorption rate was about 11.9% higher than that of the non-added sericin.
