Abstract
PURPOSE: To avoid the error in analysis without giving adverse effect on chemical reaction at reaction vessel, by eliminating the oxide attached to the wall in the reaction vessel through the use of specific mixing liquid, at titration of COD.
CONSTITUTION: A given amount of sample and preprocessing chemical liquid are put in the titration vessel 1 with the sequencer 19 and they are mixed in the mixer 15. Further, the hange-over valve 7 is connected as solid lines, and the liquid in the vessel 1 is fed to the reaction vessel 2 of negative pressure with the drive of the pump 6. Further, the pump 6 is stopped and the liquid in the vessel 2 is heated for a given time. Further, the valve 7 is selected as broken lines, and the liquid is returned in the vessel 1 from the vessel 2 increased in prssure with the drive of the pump 6. Further, traces of titration chemical liquid is dropped in the vessel 1 and mixed in the mixer 15. This operation is repeated, and when the signal end of titration is obtained from the electrode 14, the scale 18 outputs the titration weight difference. Further, the liquid in the vessel 1 is discharged and the vessel 2 is processed similarly by using the mixing liquid of preprocessing liquid and water.
