บทคัดย่อ

A simple and precise procedure using differential pulse voltammetry was developed for the assay of acetaminophen in paracetamol tablets. The peak current from acetaminophen in 0.1 mol L-1 phosphate buffer pH 7.0 was measured using a glassy carbon electrode and a Ag/AgCl reference electrode. The optimum step potential and modulation amplitude were 0.0020 and 0.0500 V, respectively. The linear calibration range was 0-300 μg ml-1, the detection limit and recovery were 0.15 μg ml-1 and 99.4%, respectively. The results were compared with those obtained by the U.S.P XXII official method.
