Abstract
PURPOSE:To wipe and discharge adhesives completely with a violent stirring of the reaction surface level under a compressed air by aynchronously operating an electric valve connected to a compressed air source and a pump of an exhaust tube with a timer mechanism. CONSTITUTION:In the drain process, a electromagnetic valve 31 is actuated with a timer mechanism 32 to feed a compressed air at the tip of an air tube 30. The compressed air bubbles to stir the reaction liquid surface 18 so strongly that adhesives on the liquid surface can be wiped completely. Then, actuated with the timer 32, a pump 23 starts to drain the reaction liquid and the liquid surface lowers intensely. The adhesives are wiped fully and drained with the liquid. After the end of the drain, the electromagnetic valve 31 and the pump 23 are halted. The subsequent purification is repeated more than one times. This prevents not only the precipitation of silver chloride on the electrode surface but also the accumulation of other floating matters thereby improving the COD analyzing accuracy remarkably.
