Quenching-Chemiluminescence Determination of Trace Amounts of
l-Tyrosine Contained in Dietary Supplement by Chemiluminescence Reaction of an Iron-Phthalocyanine Complex
Figure 3
Relationship between L-tyrosine concentration and CL intensity (PMT voltage: 730 V). [Fe-PTS]T = 4.0 × 10−5 M, [H2O2]T = 3.2 × 10−3 M, pH = 10. Curves in various concentration (M) of L-tyrosine: (1) 0, (2) 2.0 × 10−7, (3) 5.0 × 10−7, (4) 2.0 × 10−6, and (5) 5.0 × 10−6.
