AbstractA solid membrane sensor has been fabricated using polytungstoantimonate as an electroactive phase. Preliminary investigations with the membrane exhibit promising selectivity for mercury and the same can be estimated in the concentration range 5×10−5−10−1 M at pH 4–6. The potentials generated across the membrane are reproducible and the response time is less than a minute. The electrode works well even in a partially non-aqueous medium. Monovalent ions cause some interference in the working of this assembly, but bivalent and polyvalent ions do not interfere. Estimation of metal ions in the polluted waters of a local river can be successfully achieved with this membrane electrode.
