A pentachlorophenol preconcentration method using a microcolumn (20 x 2.5 mm i.d.) filled with quinolin-8-ol (oxine) immobilized on controlled-pore glass (CPG) is proposed. The method is based on retention at pH 1 and elution at pH 3 with acetonitrile-water (80 + 20). Maximum retention of pentachior
