Apparatus and method for measuring NOx and nitrification / denitrification rates during biochemical processes

摘要

A method for measuring NOx in biochemical processes which includes a) isolating a liquid sample; b) adjusting the pH or ionic strength of the sample; c) recording mV values present in the sample after predetermined time periods; d) determining NOx concentrations in the sample at each of the predetermined time periods from the mV values; e) determining the difference in NOx in the sample from the NOx concentrations at each of the predetermined time periods; and f) determining the NOx concentration of the liquid sample from the difference in NOx and the predetermined time periods.
