The development of FT-Raman techniques to quantify the hydrolysis of Cobalt (III) nitrophenylphosphate complexes using multivariate data analysis

Tshabalala, Oupa Samuel (2007-03)

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 ...
Metal ion mediated hydrolysis of 4-nitrophenylphosphate in microemulsion media: catalytic versus stoichiometric effects

Eguzozie, Kennedy Uchenna (2008-05)

The hydrolysis of 4-Nitrophenylphosphate (NPP) as model substrate in the presence of several cobalt (III) amine [N4Co(OH)(H2O)]2+ and copper bipyridyl [Cu(bpy)(H2O)2]2+ complexes in oil in water microemulsion media was ...
Nitric oxide triggered dephosphorylation reactions

Enemchukwu, Emeka Martin (2009-01)

The synergistic effect of nitric oxide toward dephosphorylation reactions involving phosphate esters was the subject of investigation in this research. Sodium nitroprusside under UV irradiations at 254nm, 365nm and white ...
Study of the effect of salt solutions on the kinetics of sucrose inversion as monitored by polarimetry

Makwakwa, Tlou Auguston (2014-06)

The acid-catalyzed inversion of sucrose is often taken as an example of a first order reaction. It is, however, influenced by many factors such as temperature, type of acid used, concentration of sucrose, and the concentration ...
