Abstract

A fiber optic sensor measured the rate of ion exchange for metal cations between a solution 4ivironrnent and silica core surface. The ion exchange of Pb was observed to be both reversible and reproducible. Further by competitive displacement of cations the exchange selectivities for a series of metals were confirmed. I.
