Direct and Indirect Spectrophotometric Determination of Paracetamol in Pharmaceutical Preparations By Oxidative Coupling With p-Amino-2-hydroxy Sodium Benzoate	2017	16	.pdf	application/pdf	4324	228	63	To a series of 25-mL volumetric flasks, different volumes (0.25 – 10 mL) of standard 50 µg.mL -1 of paracetamol solution were added followed by the addition of 1.6 mL of 0.1 M of NaIO4 solution, 0.6 mL of AHB reagent solution (1 x 10-2 M) and 2.0 mL of acetate buffer solution. Standard addition procedure: Standard addition procedure was used for the assay of paracetamol contained in pharmaceutical preparations at three concentration levels (viz. 1, 5 and 10 µg.mL-1) as follows; to a series of f ive 25-mL calibrated flasks, aliquots of the sought drug solution containing (25 or 125 or 250 µg) of paracetamol were transferred followed by the addition of ( 0, 0.5, 1.0, 1.5 and 2.0 mL) of standard paracetamol solution ( 100 µg.mL-1) respectively.	cache/iajs-965.pdf	txt/iajs-965.txt
