Popis: The synthesis and characterization of 2-pyridyl-2-thienyl-β-ketoxime and its application to the spectrophotometric determination of trace amounts of cobalt is described. The effects due to pH, time, reagent concentration, solvents, hydrochloric acid concentration and diverse ions are reported. Beer's Law is obeyed and the molar extinction coefficient at 412 nm is 2.0 X 104.
