Design of a Portable System for Spectrophotometric Determination of Uranium in Water
Abstract
Abstract In this work, sensitive chromogenic reagents were investigated to design a spectrophotometric portable system for determination of uranium in natural waters. It is found that the 2-(5-bromo-2-pyridylazo)-5-diethylaminophenol (Br-PADAP) is the best reagent for this purpose. The effect of various parameters on absorbance of Br-PADAP/ Uranium complex such as pH, masking agent, temperature, time, and uranium concentration were studied and optimized. Based on results obtained, a spectrophotometric portable system for determination of uranium in the field was designed. The results show that the system is able to determine uranium up to 0.5 ppm.
