| Abstract: | The difference of response performance of ofloxacin selective electrode based on ofloxacin-phosphomolybdic ion pair and based on ofloxacin-tetraphenylborate ion pair was studied.The result shows the ofloxacin selective electrode based on ofloxacin-tetraphenylborate ion pair as electricactive substance and tetraphenylborate as additive gave the best performance.Furthermore,the selectivity is improved.The electrode was used for pharmaceutical analysis,and the results are satisfactory. |
