| Abstract: | This paper is about the development of a kind of DrugFET sensors of ephedrine by the combination of ISFET and drug sensitive membranes. The modified ISFET of tri-o-e-β-CD is made, and used to analysis ephedrine . The sensors exhibits Nernst response for ephedrine with a slop of 58.0 mv/decade over the concentration ranges of 1.0×10-1～3.0×10-6 mol/L at pH 3.0～8.0. It has been used for determination of ephedrine in the table . The results obtained agree with the pharmacopoeia method. |
