title: A modified program for computation of formation constants of synergetic extraction complexes with two-phase titrations by using the Marquardt-Fletcher algorithm.
abstract: A modified computer program SCTPT for the computation of formation constants of extraction complexes with two-phase pH titration data by using the Marquardt-Fletcher algorithm is described. It can be used to deal with extraction systems which consist of a metal, an acidic extractant and a neutral synergistic reagent with no need of new subroutine. It has been applied successfully to the Pb-PMBP(1-phenyl-3-methyl-4-benzoyl-pyrazolone-5)-TBP (tributyl phosphate) system. The results obtained are in agreement with those published in the literature.
