The FT-Raman techniques were developed to quantify reactions that
follow on mixing aqueous solutions of bis-(1,3-diaminopropane)diaquacobalt(
III) ion ([Co(tn)2(0H)(H20)]2+) and p-nitrophenylphosphate
(PNPP).
For the development and validation of the kinetic modelling
technique, the well-studied inversion of sucrose was utilized. Rate
constants and concentrations could be estimated using calibration
solutions and modelling methods. It was found that the results
obtained are comparable to literature values. Hence this technique
could be further used for the [Co(tn)2(0H)(H20)]2+ assisted
hydrolysis of PNPP.
It was found that rate constants where the pH is maintained at 7.30
give results which differ from those where the pH is started at 7.30
and allowed to change during the reaction. The average rate
constant for 2:1 ([Co(tn)2(0H)(H20)]2+:PNPP reactions was found to
be approximately 3 x 104 times the unassisted PNPP hydrolysis rate. / Chemistry / M. Sc. (Chemistry)
