Membrane Sensors for the Selective Determination of Donepezil Hydrochloride

Membrane sensors for the selective determination of thiopental.

Novel miniaturized polyurethane (PU) membrane sensors in an all-solid state graphite support were developed, electrochemically evaluated and used for the assay of thiopental drug. The thiopental (T) sensors are based on the formation of ion-association complexes of thiopental with copper(II) and cobalt(II)-bathophenanthroline (bphen) counter anions as electroactive materials dispersed in a poly...

Ion Selective PVC Membrane Electrode for the Determination of Methacycline Hydrochloride in Pharmaceutical Formulation

A plastic membrane electrode for the determination of methacycline hydrochloride was fabricated based on the use of methacycline-tetraphenylborate as the electroactive substance, and dioctylphtalate as the plasticizing agent. It was found that the potential responses of the electrode were influenced by pH of the tested solution when pH>3. Under the condition of pH 2.6, the linear response range...

Disposable screen-printed sensors for determination of duloxetine hydrochloride

A screen-printed disposable electrode system for the determination of duloxetine hydrochloride (DL) was developed using screen-printing technology. Homemade printing has been characterized and optimized on the basis of effects of the modifier and plasticizers. The fabricated bi-electrode potentiometric strip containing both working and reference electrodes was used as duloxetine hydrochloride s...
