Abstract

PURPOSE:To rapidly and easily detect the deterioration extent of a liq. etchant by depositing an etched metal on an electrode dipped in the etchant, connecting the electrode to another electrode, and measuring the dissolution time of the deposited metal. CONSTITUTION:The first electrode 5 of a platinum plate and the second electrode 6 of a discoid platinum plate are dipped in the liq. etchant 10 sampled in a measuring vessel 9. An electric current is supplied for a specified time between both electrodes 5 and 6 from a constant-current power source 1 to deposit the etched metal in the etchant 9 on the second electrode 6. A relay 3 is then switched, the second electrode 6 is connected to the third electrode 7 of a platinum wire through a potential difference measuring device 2, and a closed circuit is formed. As a result, a potential difference is produced between both electrodes 6 and 7, and the deposited metal is dissolved. When the dissolution is finished and the potential difference is diminished to zero, the etching rate of the etchant 10 is computed by a computing circuit 8 from the amt. of the deposited metal and the dissolution time, and the deterioration extent of the etchant is detected.
