STABILITY-INDICATING POTENTIOMETRIC METHOD FOR THE DETERMINATION OF CYCLOBENZAPRINE HCL USING TWO CARBON PASTE ION-SELECTIVE ELECTRODES
Journal Title: Innoriginal: International Journal Of Sciences - Year 2018, Vol 5, Issue 6
Abstract
Objective: Two sensitive and selective carbon paste electrodes were developed and investigated for determination of cyclobenzaprine hydrochloride. Methods: Sensor I was developed using ammomium renikate as an anion exchanger and dibutyl phthalate as a plasticizer while sensor II was developed using phosphotungestic acid as an anion exchanger and dibutyl phthalate as a plasticizer. Results: The proposed electrodes showed a near-nernsation response in the range from 1.00×10-4-1.00×10-2 M and 5.00×10-5-1.00×10-2 M for sensor I and sensor II, respectively. The selectivity of the proposed electrodes to a number of interferences was investigated. Conclusion: Cyclobenzaprine hydrochloride was successfully determined in pure form, pharmaceutical formulation and in the presence of anthraquinone (its oxidative degradation product) using the two proposed sensors.
