Determination of 2,4‐Dichlorophenoxy Acetic Acid in Surface Waters
In this study, the colorimetric and ultraviolet methods were adapted and were modified for the quantitative determination of 2, 4‐D in surface waters. Principal interferences were found to be the naturally occurring colored compounds and 2, 4‐dichlorophenol, which is present as an impurity in most commercial formulations of 2, 4‐D. These interferences were separated by the partition chromatographic procedure of Gordon and Beroza. Ester of 2, 4‐D are hydrolyzed to the free acid by potassium hydroxide in diethylene glycol.
