摘要:

A new spectrofluorimetric method for the determination of zinc using pyridoxal nicotinylhydrazone as the reagent has been developed. This system forms a ternary complex with ammonia, ethylenediamine or pyridine with a stoichiometry ratio of 1:1:1. The interferences of foreign ions have been determined.
