| Abstract: | The drug carrying properties of starch micro-sphere were evaluated in three different media: 0.1mol/L hydrochloric acid, pH7.4 phosphate buffer succi(PBS), physiological saline(PS) with methylene blue as model drug. The adsorptive mechanism of starch micro-sphere was studied by means of eletrachemical method using ascorbic acid(AA) as model drug, using starch micro-sphere as agent prepare chemical modefied carbonic parafin electrode(CMCPE). |

| Keywords: | starch micro-sphere adsorptive mechanism modified electrode model drug |
