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