In this work the modified iodine-coated polycrystalline platinum electrode was used to develope a voltammetric sensor for paracetamol determination in pharmaceutical formulations. The optimized experimental parameters for the determination of paracetamol were using 0.5 M H 2 SO 4 as a supporting electrolyte with a scan rate of 50 mV/s. The anodic p...

... standard of known concentration, 50 ppm, were spiked into a samples of tablet solutions in order to evaluate the percental recovery for each brand of paracetamol. As listed in Table 1, the recovery values were found between 101.42 ± 0.64 and 104.05 ± 4.19 for all samples of paracetamol brands which showing the appropriateness of the iodine-coated platinum electrode for the quantitative analysis of paracetamol in pharmaceutical formulations. ...Similar publications
In this work, the utilization of the modified iodine-coated polycrystalline platinum electrode as a voltammetric sensor for copper determination in pharmaceutical formulations was reported. The optimized experimental parameters for the determination of copper were using 0.1M KCl as a supporting electrolyte with a scan rate of 50 mV/s, deposition po...

... Given its significance, numerous researchers have focused on analyzing this drug in its different forms, including tablets, syrups, and injections. Methods employed for estimating paracetamol concentrations include high-performance liquid chromatography [4][5][6], We observe that numerous researchers have heavily relied on optical spectroscopic methods for the quantitative estimation of various drugs [7], including those currently under investigation; flow injection analysis [8], first derivative spectroscopy [9,10], UV-visible spectroscopy [11,12], and electrochemical techniques [13,14]. Figure 1 illustrates the chemical structure of paracetamol. ...
