Spectrophotometric determination of copper in alloys with di-2-pyridylglyoxal-2-quinolylhydrazone

HEMANT KULSHRESHTHA, SATYA KUMAR, R P SINGH

Abstract


D-2-Pyridylglyoxal-2-quinolylhydrazone reacts with Cu(II) to form red coloured complex suitable for spectrophotometric determination of metal. The complex contains metal and ligand in 1 : 2 molar ratio and molar absorptivity is 3' 5 X 104 L mole -1 cmo-Copper has also been determined in several alloys.

Keywords


Di-2-pyridy!glyoxal-2-quinolylhydrazone (PQH); copper; spectrophotometric determination; alloys.
