title: Flow-injection spectrophotometric determination of cadmium with quinolylazo compound after on-line separation using a silica gel column.
abstract: 2-[2-(4-Methylquinolyl)azo]-5-diethylaminophenol(QADP) reacts with cadmium in aqueous ethanol and the molar absorptivity of the QADP-cadmium complex is the highest (1.51 x 1O(5)M(-1) cm(-1), gamma(max) 569 nm) of the reagents reported previously. A flow-injection spectrophotometric determination of cadmium with QADP after on-line separation using silica gel column was proposed. A 450 mug/l cadmium concentration could be determined in the presence of 13 mg/l zinc, 83 mg/l lead and 11 mg/l iron.
