A solid chelating compound phenanthrenequinone monoxime (PQM) supported on naphthalene provides a rapid and economical means of preconcentration and separation of copper from the aqueous samples. Copper forms a complex with PQM supported on naphthalene in the column at pH 6.1-8.4 with a flow rate of 1 ml/min. The metal complex and naphthalene are dissolved out from the column with 5 ml of DMP and the absorbance is measured at 470 nm against reagent blank. Beer's law is obeyed in the concentration range 0.6-9.6 {mu}g of copper in 5 ml of DMF. The molar absorptivity and sensitivity are 6.3 {times} 10{sup 4} L mol{sup {minus} 1} cm{sup {minus} 1} and 0.001 {mu}g cm{sup {minus} 2} respectively.
