| Abstract: | The theoretical predictions are presented about kinetic effect of complex formation on direct titration curves and data interpretations.The kinetic equation for 1:1 complexation is derived for analysis of concentration-time curves.The concept of titration equilibrum time(T) is introduced and calculated by means of computer in different stability constant(K'ML) and titration procedures.The results will provide a theoretical basis for application of direct titration in natural water. |
