A graph is plotted o in C cm against pH

A graph is plotted σo in (C/cm2) against PSI-6206 for NC/NB, P(IA/MAA)-g-NC/NB ( Fig. 5). The pH at which σo is equal to zero is taken as pHpzc.

The elemental distribution over the surface is opsins confirmed by EDS analysis.
The EDS spectra of P(IA/MAA)-g-NC/NB and U(VI)-P(IA/MAA)-g-NC/NB are in Fig. 4. The constituents C, O, N give major peaks and the peak intensity shows the grafting taken place in the polymer. New peaks observed in the EDS spectrum of U(VI)-P(IA/MAA)-g-NC/NB around 2, 3-4, and 14 keV the decreased intensity of C and O indicates carboxyl co-ordination mechanism attributed to the adsorption process of U(VI).
