AN ASSESSMENT OF A RAPID AND CONVENIENT SPECTROPHOTOMETRY ADAPTATION OF THE WINKLER PROCEDURE FOR THE DETERMINATION OF DISSOLVED OXYGEN IN FRESH WATERS

Abstract

The use of a spectrophotometric adaptation of the standard Winkler procedure to measure the dissolved oxygen content of water samples is described and assessed. The technique allows the rapid processing of routine samples and the accuracy, precision and sensitivity of the technique are comparable to the Winkler titration procedure. The modified technique is recommended for routine use in limnological studies.
