An ion exchange chromatographic method has been developed for the determination of urea in freshwater, rainwater, and water-extracted aerosol samples. The method provides a fast and reliable way to determine the concentration of urea without the use of harmful chemicals or large amounts of time devoted to sample preparation. The method utilizes a Dionex IonPac CS12 cation exchange column and UV detection at 190 nm. A comparison between the new method described in this manuscript and a previously published method for urea determination in rainwater and water-extracted aerosol samples is also presented. This comparison shows potential interferences from other organic N compounds similar to urea when using the previously published method. Tests utilizing various pH values and the enzyme urease also confirmed the ability of the new method to determine the concentration of urea within atmospheric aerosols and natural waters. |
