چکیده
|
In this research, the determination and complexation process between 3,3’-(2,2’-(4-methyl-phenylenesulfonamido)bis(ethane-2,1-diyl)) bis(1-benzyl-3h-benzo[d]imidazol-1-ium)dibromide with ni2+, zn2+, pd2+, ag+ , and hg2+ cations in the binary mixture of methanol (meoh) and water (h2 o) at different temperatures (15, 25, 35 and 45ºc) were studied using a conductometric method. the results show that the stoichiometry of the complexes in all binary mixed solvents for ni2+, zn2+, and pd2+ were 1:1 (m:l), while in other cases 1:2 (m:l) and 2:1(m:l). the stability constants (log ) of complex formation have been determined by fitting molar conductivity curves using a computer program (genplot). the obtained data shows that in the pure methanol solvent system, the stability order is ni2+< pd2+
