Permeation liquid membrane as a tool for monitoring bioavailable Pb in natural waters

In order to predict metal bioavailability by microorganisms in natural waters, analytical speciation techniques such as the permeation liquid membrane (PLM) are required. A planar sheet PLM has been characterized by measuring Pb fluxes in the absence and p ...
