SELECTIVE SPECTROPHOTOMETRIC DETERMINATION OF FENOTEROL BY THREE DIFFERENT METHODS.

Selective extraction spectrophotometric determination

development of different optical methods for determination of glucose using cadmium telluride quantum dots and silver nanoparticles

a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...

Simultaneous spectrophotometric determination of lidocaine and hydrocortisone acetate in pharmaceutical preparations by multivariate calibration methods

The multivariate calibration method, partial least square regression (PLS) was applied for thesimultaneous spectrophotometric determination of Lidocaine (LID) and Hydrocortisone acetate(HCA) in their mixtures. The parameters of chemometric technique were optimized and theproposed method was validated with synthetic samples and applied to analyze these drugs inpharmaceutical products with good a...

Selective and validated spectrophotometric methods for determination of ganciclovir with PDAB and Folin’s reagents

Two simple, sensitive, selective, accurate and precise methods (Methods A and B) have been developed for the quantitative estimation of ganciclovir in bulk drug and its pharmaceutical formulations. In Method A, presence of amino group in ganciclovir enables the use of condensation reaction with p-dimethylamino benzaldehyde, forming the greenish yellow colored complex due to the formation of Sch...

Sensitive and Selective Spectrophotometric Methods for the Determination of Cisaprid, Metoclopramide Hydrochloride, Sulphadoxine and Sulphamethoxazole

Two simple, sensitive and selective spectrophotometric methods were developed for the determination of cisapride (CPD), metoclopramide hydrochloride (MCP), sulphadoxine (SDX) and sulphamethoxazole (SMX) containing aromatic primary amino group. The methods are based on the interaction of diazotised drugs with iminodibenzyl (IDB) and 3-chloroiminodibenzyl (Cl-IDB) (new spectrophotometric reagents...
