Determination Micro Spectrohotometric of Pyridoxine Hydrochloride and Nicotinamide via Derivative Spectrophotometry First and Second

Abstract

A simple, sensitive and accurate spectrophotometric method for determination of PYR.HCl and NTA in pure and pharmaceutical forms. The method based on group of known digital data used to separate the response signals for sample contains the two components without need to separating via first and second derivative of spectra. The method obtained obeying to the Beers law in the concentration range between )5-45 µg.ml-1( for two components in the presence of PYR. HCl )15µg.ml-1( and NTA (5µg.ml-1) with another components at wavelength (210 nm ) respectively . The Rec % range was between ) 98.5354 - 103.4335 % (and RSD% (0.0864 - 0.1487 %), LOD) 1.0822 µg.ml-1, ( LOQ ( 3.6075 µg.ml-1 (PYR.HCl in presence of NTA, The Rec% range was between )96.1418 - 102.9273 % (and RSD% (0.2165–0.4933 % ), LOD (0.7273µg.ml-1 ,(LOQ (2.4252 µg.ml-1( NTA in presence of PYR.
