Mini Electrode Based on Chitosan-Activated Carbon Membrane for Detection of Paracetamol in Herbal Medicine

A tube type mini electrode has been made to detect paracetamol levels in herbal medicine, the is of a glass with diameter 0.7 cm, length 3 cm. As membrane mixture chitosan, activated carbon from rice husk, and cetyl trimethyl ammonium (CTA)-paracetamol. The internal solution standard 0.01 M phosphoric acid pH 2. average sensitivity sensor (22.60 ± 0.01) mV/decade linear concentration range 10-6 – 5x10-3 M, an recovery (90.6 0.5) %. Paracetamol electrodes can be applied samples medicine on market, error (9.4 0.1)
