| Abstract: | The electrochemistry behavior of Phenoxybenzamie Hydrochloride had been studied in linear scanning polarographic method and cyclic voltammetry. In 0.06 mol.L-1 NH3-NH4Ci buffer solution of pH 8.55, a sensitive reduetive wave of Phenoxybenzamie Hydrochloride appeared at -1.193 V （vs.SCE）. The linear relationship between the peak current and the Phenoxybenzamie Hydrochloride concentration in the range of 0.01 - 5.00 mg.L-1 （r=0.9974, n=10） were observed, the detection limit of the method is 0.008 mg.L-1. RSD found from the data of 6 independent determinations at the concentration level of 0.50 mg.L-1 was 0.75%, recoveries obtained were in the range of 97.8%-109.9%. This Pbenoxybenzamie Hydrochloride electrochemical characteristic property may be used for determining the contents in tablets. |
