Spectrofluorimetric Determination of Trace Terbium(Ⅲ) Using 2,6-Bis-(1'-phenyl-3'-methyl-5'-oxopyrazole-4') Pyridinediacyl and N-Cetylpyridium Bromide
摘要:
A new spectrofluorimetric method for determination of trace terbium based on its reaction with 2,6-bis-(1'-phenyl-3'-methyl-5'-oxopyrazole-4') pyridinediacyl (H2PMBPP) and N-cetylpyridium bromide (CPB), at an apparent pH=5.0 provided by a hexamethylenetetramine (5% w/w)-hydrochloric acid buffer, is proposed. The calibration graph is linear in the range from 1.43×10-5 to 0.1589 μg/ml.
