摘要：The effect of some biologically significant transition metal complexes such as [Fe(bpy)Cl4] [bpy-H], [Co(bpy)(phen)2](NO3)2·2H2O, [Fe(PDCl4][PD-H], [Cu(L)(NO3)2], [Cu(phen)2] Cl2·2H2O and [Cu(PD)(phen)2](NO3)2·2H2O (L=3,14-diethyl-2,6,13,17-tetraazatricyclo (16,4,07,12)docosane, bpy=2,2?-bipyridine, PD =1,10-phenanthroline-5,6-dione, phen=1,10-phenanthroline) on the critical micelle concentration (CMC) of an anionic surfactant, sodium dodecyl sulfate (SDS) were studied by conductance measurement method. The investigation was performed in the additives concentration ranging from 2.0 × 10-4 M to 8.0 × 10-4 M and at temperature ranging from 20°C to 35°C with an interval of 5°C. Different micellar parameters such as CMC, degree of counter ion dissociation (?), degrees of counter ion binding (f), binding constant (Kb) as well as thermodynamic parameters were determined using the conductivity data. © 2014 JSR Publications.
