Application of flow injection potentiometry to the determination of chloride in various matrices

摘要: The preparation and performance of a tubular chloride ion selective electrode for flow injection potentiometry is presented. influence system parameters on sensitivity, detection limit, response time sample throughput are investigated. It shown that 60–200 samples can be processed per hour within the concentration range 0.1–10,000 mg/l. precision generally better than 1% r.s.d. over entire range. Application proposed method to analysis tap mineral water, emission control hydrogen determination in pure silicon nitride give results very well comparable other methods.
