Abstract:A method of flow injection analysis was introduced into the spectrophot-metric system of Cd-DB-CDAA complex for the determination of trace Cd ( Ⅱ ) This method was simple,rapid and reproducible one Beer's law was obeyed with in the rang from 0. 00 to 2.μg/ml for cd(Ⅱ) ,and the detection limit was 0. 01 μg/ml After soyand vinegar was separated by the paper chromatography,the method can be used in the deter-minationn of trace Cd(Ⅱ ) with satisfactory results.
Keywords:Flaw injection analysis  Spectrophotometry  Cadmium  soy    vinegar .
