This method is suitable for the
determination of nitrate in effluent
samples in the concentration range
0.05 to 1 mg/l. Higher levels can
also be accommodated by including
a dilution system into the manifold.
The precision of the method, as
determined by the relative standard
deviation (sr), is 0.01 at the 0.5 mg/l
level. A sampling frequency of 30
measurements per hour is obtained.
No major interferences are
anticipated.
