Measurement of pAg in natural water samples

摘要

AbstractA method has been developed for the determination of pAg in natural water samples using a direct potentiometric measurement technique. Calibration standards have been prepared, and linearity of the technique has been demonstrated for the pAg range of 2 to 11, with Nernstian response. The method has been applied to samples of several natural waters in the United States and the results are tabulated. The measured pAg values of natural waters were within the range of 8.8 to 12.0, corresponding to silver ion activities of 0.0001 to 0.2 μg/L
