| Abstract: | A methylene blue polyvinyl chloride membrane electrode based on MB-phosphotungstate ion-pair complex as electroactive material is described. The response is linear over 1x10-3 -1×10-6 mol dm-3 of dye solution, with a slope of 51.5±0.8 mv/decade (pH range 3.0- 10.0). The detection limit is 6.79 × 10-7mol dm-3. The elcctrode is stable and shows good reproducibility and fast response. The electrode has been used successfully for the determination of methylene blue in injections. These results are in good agreement with those obtained with potentiometric method and USP standard procedures. |
