原始语种摘要: Paracetamol with 1-Naphthol gave an azodye and the concentration of paracetamol was investigated spectrophotometrically. The dye formed with 1-Naphthol as a coupling agent followed Beer Lambert’s law within the range of 2 – 10 μgmL-1 of paracetamol at a lambda max (λmax) of 505nm. The molar absorptively of the azodye coupled with 1-Naphthol was found to be 1.6973×104 dm3mol-1cm-1, r2 was 0.9974. P value was found to be 0.013 at 95% confidence. LOD was 0. 02 μgmL-1 while LOQ was 0. 10 μgmL-1. The coupling agent has been applied successfully for the analysis of paracetamol in pharmaceutical preparations such as boska, ibex, mixagrip, norgesis and procold with the recovery of 101.27 %, 98.98 %, 99.47 %, 98.28 % and 101.6 % respectively. The relative standard deviation of all the five samples...
