摘要: Abstract A spectrophotometric study is presented on the formation of colored complexes: disodium salt 1,10-phenanthroline-4,7-diphenyl- p -disulfonic acid/metallic ions. In this paper, relationship existing between ionic radius cation and stoichiometries complex or complexes formed found, giving values apparent constants obtained for each them. The optimum pH reaction also established, as well its parameters.
