A polystyrene-based membrane electrode sensitive to molybdate ions.
A polystyrene-based zirconium oxide membrane has been used to determine the concentration of molybdate ions in the range 0.5-10(-3)M and pH range 7-11. The response time is about 20 sec and the electrode remains usable for at least 6 months. It can also be used as an indicator electrode for titrations involving molybdate ions. Univalent anions interfere more strongly than bivalent and multivalent anions.
