XPS of Pb(NO3)2, PAPVAM and PAPVAM with Pb(II). By XPS, interaction of different atoms can be confirmed.
Steps to reproduce
Pb (II) was absorbed by PAPVAM then dried in an oven at 50oC. The elements on the surface of the dried PAPVAM and PAPVAM with Pb (II) were characterized by XPS (Thermo ESCALAB 250Xi, USA). To do so, monochromatic Al K radiation (1486.6 eV) was used at 150 W.
