Spectrophotometric determination of ceterizine hydrochloride with Alizarin Red S.
A simple, rapid and sensitive spectrophotometric method has been developed for the assay of ceterizine hydrochloride (CTZH) in bulk drug and its pharmaceutical preparations. This method is based on the ion-pair complex reaction between CTZH and Alizarin Red S in Clarks-Lubs buffer. The chromogen being extractable with chloroform, could be measured quantitatively at 440 nm. All variables were st...
متن کاملElectrocoagulation removal of anthraquinone dye Alizarin Red S from aqueous solution using aluminum electrodes:
Electrocoagulation (EC) was used for the removal of anthraquinone dye, Alizarin Red S (ARS) from aqueous solution. The process was carried out in a batch electrochemical cell with Al electrodes in a monopolar connection. The effects of some important parameters such as current density, pH, temperature and initial dye concentration, on the process were investigated. Equilibrium was attained afte...
متن کاملSelective Spectrophotometric Determination of Metformin Hydrochloride in Pharmaceuticals and Urine Using Two Nitrophenols as Chromogenic Agents
Metformin hydrochloride (MFH) is an oral anti-diabetic drug of biguanide class. Two selective spectrophotometric methods were presented for the determination of MFH in pharmaceuticals. The methods were based on the measurement of yellow-coloured charge-transfer complexes formed between MFH and two poly-nitrophenols, namely, 2,4-dinitrophenol (DNP method, at 405 nm) and picric acid (PA met...
متن کاملSpectrophotometric Determination of Ascorbic acid in Aqueous Solutions and in Pharmaceuticals formulations
A new sensitive colorimetric method for determination of ascorbic acid tablet in aqueous solution. The method is based on the formation of colored azo dye by diazotization of 2, 4dichloroaniline followed by azo-coupling reaction between the resulting product and ascorbic acid. The optimum conditions that gave maximum absorption of azo dye at535nm, with best concentration of reactant and order o...
متن کاملPhototransformation of anthraquinone-2-sulphonate in aqueous solution.
Anthraquinone-2-sulphonate (AQ2S) is a triplet sensitiser that has recently been used to model the photoreactivity of chromophoric dissolved organic matter (CDOM). We show that the photolysis quantum yield of AQ2S under UVA irradiation varies from (3.4 ± 0.2) × 10(-3) at μM AQ2S levels to (1.8 ± 0.1) × 10(-2) at 3 mM AQ2S (μ±σ). This trend is consistent with a combination of direct phototransfo...
