METHOD FOR WASHING ELECTRODE FOR TITRATION OF POTENTIAL DIFFERENCE

摘要

PURPOSE:To make it possible to effectively wash an electrode without damaging the electrode and dissolving an adhered precipitate, by mixing an extremely small amount of filter paper pump in washing solutions alternately arranged along with solutions to be tested on a turntable. CONSTITUTION:Filter paper pulp prepared by beating filter paper in water is added to a washing solution under stirring in an amount of 0.2-3g per 100ml of said washing solution on a dry wt. basis to prepare a washing solution. Thus prepared washing solutions and solutions to be tested each having a stirrer put therein are alternately arranged on a turntable so as to leave intervals of about 2-5cm therebetween. A time of 3-7min required in titration and a time of about 1-2min required in washing an electrode are preset to intermittently perform titration and the washing of the electrode.
