"Study On The Dissolution Rate Of Acetaminophen Tablets By Flow Injection Analysis"
Zhongguo Yaoke Daxue Xuebao 1988 Volume 19, Issue 4 Pages 294-296
Jiang Xinru, Mei Rongfen and An Dengkui

Abstract: The dissolution rate of acetaminophen(paracetamol) tablets by using flow injection analysis coupled with UV spectrophotometer was studied. The sample solution (102 µL) was injected into the carrier stream, which was a 0.01 mol/L sodium hydroxide solution. Acetaminophen in the range of 2-20 µg/mL can be rapidly determined with a precision of 0.18%. A rate of measurements was 120-180 times per hour. The average recovery of acetaminophen was 100.5±0.37%, and the coefficient of variation was 0.67%. Results obtained by the proposed method were found to be in good agreement with those obtained by the official technique.

"Discussion On"
Anal. Chim. Acta 1993 Volume 278, Issue 1 Pages 205-206
Wei Li and Jian Chen, Deng-Kui An*

Abstract: The cited paper (Zhu et al., Anal. Chim. Acta, 1992, 256, 97) describes an online determination of bromide ion in spent brine by combining fiber-optic techniques, continuous-flow sampling and a dual absorption cell system. Some errors have been found in the mathematical treatment of the dual cell system and the necessary corrections are presented.
