제목 Depolymerization of Sodium alginate by e-beam irradiation and hydrogen peroxide
초록 An alginate has various novel biological effects such as plant growth promotion, antibacterial activity, andgelling agent. Even though alginate has been used in a wide range of fields, high molecular weigh alginate limits its application of specific fields caused by its high viscosity and poor solubility in water.A variety of methods has been used to get the low molecular weight alginate by traditional methods.In this study, hydrogen peroxide and the e-beam irradiationwere used in depolymerization of sodium alginate. As a result, hydrogen peroxide and e-beam irradiation are much more effective than any other methods in lowering the molecular weight of sodium alginate. Controlling the molecular weight of sodium alginate was charaterized by using solution viscometry, GPC, FT-IR, 1H-NMR and 13C-NMR.
