AMMONIAC NITROGEN MEASUREMENT METHOD OF COULOMETRIC TITRATION SYSTEM, AND DEVICE THEREOF

摘要

PROBLEM TO BE SOLVED: To provide an ammoniac nitrogen measurement device of coulometric titration system that can measure up to 0.05 mg/L as a lower limit of measurement.;SOLUTION: A surface area of a cathode used as an electrolysis electrode is set to 1/50 to 1/100 of a surface area of an anode, and current density of the cathode is set to 0.1 to 0.2 A/cm². Consequently, the ammoniac nitrogen with 0.05 mg/L can be measured.;COPYRIGHT: (C)2013,JPO&INPIT
