Catalytic Spectrophotometric Determination of Traces of Tellurium (IV)
A Simple, rapid and sensitive method has been developed for determination of trances of tellurium (VI) (0.096-1.250 mg/mL) based on its catalytic effect on the reduction reaction of toluidine blue by sulfide ion at pH 4. The reaction is monitored spectrophotometrically by measuring the decrease in absorbance of the dyestuff at 628 nm by the fixed time method. The detection...

متن کاملSpectrophotometric Determination of Copper
The utility of Patton and Reeder’s indicator, HHSNNA, for the trace spectrophotometric and visual colorimetric determination of Cu 2+ is explored. A wine red complex of composition 1:1 is found to be formed between Cu 2+ and HHSNNA. The complex has λmax at 530 nm with ε = 25,558 L mole -1 cm -1 and is stable for more than 2 hrs. Beer’s law is obeyed between 0 to 1.5 ppm. The developed procedure...
متن کاملSpectrophotometric determination of chlorodiazepoxide
Simple, rapid and sensitive spectrophotometric methods were developed for the determination of chlorodiazepoxide drugs in pharmaceutical dosage forms. This method is based on ion pair and charge transfer complexation reactions. The method is based on the reaction of the chlorodiazepoxide drug with Mo(V)–thiocyanate in hydrochloric acid medium followed by an extraction of the coloured ion-pair w...
متن کاملDirect Spectrophotometric determination of Aluminum (III) using 5-Bromo-2-hydroxy-3-methoxybenzaldehyde-P- hydroxybenzoic hydrazone
Highly sensitive and selective direct spectrophotometric method is proposed for the determination of aluminium in various real samples. 5-Bromo-2-hydroxy-3-methoxybenzaldehyde-phydroxybenzoic hydrazone reacts with Al(III) forming yellow coloured soluble complex in aqueous dimethyl formamide which has a λmax at 390 nm in the pH range 3.0-7.0. The system obeyed Beer’s law in the range 0.053 – 0.7...
