Method for measuring phosphoric acid
专利汇可以提供Method for measuring phosphoric acid专利检索，专利查询，专利分析的服务。并且PURPOSE: To make it possible to stably, economically and automatically measure the concn. of phosphorus in a specimen, by always recirculating an acidic molybdenic acid solution through a flow passage containing an electrolytic cell to which constant potential was applied.
CONSTITUTION: An acidic molybdenic acid solution is passes a three-way valve 3 from an acidic molybdenic acid solution tank 1 to be sent to an electrolytic cell 6 through a specimen injection valve 4 and a mixing pipe 5 and further passes through a three-way valve 7 to be discharged to a waste solution sump 8. By this operation, the flow passage of the valves 3, 4 is changed over to a recirculation mode and the acidic molybdenic acid solution is recirculated through a flow passage 9. Constant potential is applied to the cell 6 by a potentiostat 10 to stabilize a background current. Next, a definite amount of the specimen preliminarily converted to an orthophosphoric acid form is supplied from the valve 4 at the time of measurement and the oxidative decomposition of phosphorus is performed by an oxidizing agent. This specimen containing orthophosphoric acid and the molybdenic acid solution form phosphoric molibdate in a mixing tube 5 to undergo constant potential electrolysis in the cell 6. The concn. of phosphorus is measured from the quantity of electricity required in electrolysis at this time.
