| Abstract: | A new analytical method of chlobamoli hydrochloride isestalished. The chlobamoli hydrochloride sensitive field effect transistor is prepared by the combination of ISFET and a drug sensitive membrane which is composed of active material silicotungstic acid, plasticizer dioctyl phthalate, PVC powder and tetrahydrofuran solvent. The sensor can respond to chlobamoli hydro chloride with the slope of 60 mV/dec. in the concentration range of 1.00×10-1～1.50×10-5mol/L at pH=4.5～8.2. The detection limit is 8.5×10-6mol/L. It has been used for the determination of chlobamoli hydrochloride in medicinal tablet. The results agree with those of the spectroptotometry. |
