Extractive Spectrophotometric Determination of Molybdenum using p-Chloroisonitroso Acetophenone Hydrazone

Abstract

Separation technique like solvent extraction can be advantageously
employed for the determination of metals at low concentration
in micrograms using spectrophotometric methods. Hydrazoxine
has been used for the extraction and spectrophotometric determination
of metals at trace level as well as for the studies of transition
metals in complex form. In the present paper, solvent extraction
technique has been used to develop methods for the separation and
spectrophotometric determination of Mo(VI) with p-chloroisonitroso-
acetophenone hydrazone (HICAPH) prepared as per procedure
reported by Dey using p-chloroisonitroso acetophenone.
Complex formed with p-chloroisonitroso acetophenone hydrazone
was extracted into chloroform from aqueous solution in the pH
range 8 to 8.5. The ,absorption maxima was also tried for the extracted
species and Beer's law was also studied for its applicability.
In this, interference from the foreign ion has also been examined.
