Coulometric Titration of Ethylenediaminetetraacetate (EDTA) with Spectrophotometric Endpoint Detection: An Experiment for the Instrumental Analysis Laboratory
Williams, Kathryn R.; Young, Vaneica Y.; Killian, Benjamin J.
Journal of Chemical Education, v88 n3 p315-316 Mar 2011
Ethylenediaminetetraacetate (EDTA) is commonly used as an anticoagulant in blood-collection procedures. In this experiment for the instrumental analysis laboratory, students determine the quantity of EDTA in commercial collection tubes by coulometric titration with electrolytically generated Cu[superscript 2+]. The endpoint is detected spectrophotometrically using a UV-vis spectrophotometer equipped with a fiber optic probe. Students gain experience with two instrumental methods and learn about a practical application of complexation chemistry. (Contains 1 table and 1 figure.)
