专利汇可以提供Ion density measurement专利检索,专利查询,专利分析的服务。并且PURPOSE: To measure ion density by a current flowing through a battery, by a method wherein an electrochemical ion sensor having ion selectivity for ions to be inspected and a high electrode resistance and a reference electrode are immersed into a solution to be inspected to construct a battery and the potential of the sensor is regulated for the reference electrode.
CONSTITUTION: A pH sensor uses a cylinder of a specified size made up of a basal plane pyrolitic graphite BPG 11 plate, a lead 16 is connected to the bottom surface 11b by a conducting adhesive 15 and the tip 11a of the BPG11 is insulated by converting it with a conducting oxide polymer film 13 to form an electronic oxide polymerization covered electrode. The covered electrode thus obtained is washed and dried and then, a water surface ion selecting film 14 applied over the polymer film 13 to make a pH sensor. An electrochemical ion sensor 23 made up of this pH sensor and a reference electrode 24 are immersed into a solution 22 to be inspected in a tank 21 to build a battery. Then, a voltage is applied from a potentiostat 25, the potential of the sensor 23 is regulated with the electrode 24 and current flowing through the battery is measured with an ammeter 26, thereby enabling accurate measurement of ion density.
