摘 要:A new spectrofluorimetric method for determination of trace terbium based on its reaction with 2.6-his-(1 -phenyl-3 -methyl-5 - pyridinediacyl (H_2PMBPP) and N- cetylpyridium bromide (CPB). at an apparent pH=5.0 provided by a hexamethylenetetramine (5% w/w)-hydrochloric acid buffer,is propesed. The calibration graph is linear in the ran ge from
