Abstract

Herein, we adopted means of LA-ICP-MS to determine the element composition of fouling developed in the end of 24 h filtration of synthesized low-level radioactive liquid. Our experiment results showed that cations possessing identical charges would deposit together, while observed low mass recoveries of Cu, Fe, and Ag ions suggested they have deposited deep in membranes than others. It was therefore speculated that fouling developed might be attributed to the formation of precipitate of high affinity transition metal oxides such as ferric hydroxides and low solubility element such as the hydroxides of Mg and Ca ions.
