摘要：

A relatively rapid, economic and robust procedure is described for the alpha-radiometric analysts of natural waters The analysis is performed by alpha-spectroscopy after pre-concentration and separation of uranium by cation-exchange (Chelex-100) and filially its electrodeposition on stainless steel discs The method has been successfully applied to 100 ml samples of natural waters (e.g. ground- and seawaters) resulting in high-quality spectra for measurement times less than 34 Is In addition, a main advantage of the procedure (particularly for routine measurements) is that there is no consumption of organic solvents and multiple recycling/reuse of the resin is possible.
