Ammonical nitrogen (NH4 +-N) was determined by KCl extraction method followed by phenate method (APHA 2005).
Total ammonia was analyzed weekly using the phenate method and nitrite using the sulfanilamide-NED method (APHA et al. 1995).
N-NH4+ was assessed by the phenate method (4500-NH3).
Total nitrogen and phosphorus were analyzed by a colorimetric automated phenate method, following digestion by metal-catalyzed acid and persulfate techniques, respectively (U.S. EPA 1983).
PO4 3−, NO3 N, SO4 2− and NH4 N were determined spectrophotometrically (HACH DR/5000 U) using Ammonium molybdenum method, phenol-disulfonic acid method, barium-chloride method and phenate method, respectively.
The analysis for NH4 + N in the filtered sample was done using Phenate Method (APHA 2005).
The concentration of ammonia was measured using the phenate method [ 26].
There will also be performances by Eclectic Method and Body Language.
Carroll, by method and temperament, is an oddball.
Nimoy, by contrast, was "method" through and through.
