Abstract
Two derivatives of vitamin B12, aquocyanocobalt-(III) heptapropylcobyr inate (HPC) and aquocyanocobalt-(III) heptamethylcobyrinate (HMC), wer e synthesized and used as anion carriers in supported liquid membranes . More efficient transport was observed when the more lipophilic carri er (i.e., HPC) was used. The effect of several parameters such as the carrier concentration and the composition of the stripping solution on the permeability of the membranes were investigated. The properties o f these transport systems were related to the response behavior of ISE s that are based on the HPC carrier.
