Interactions of no-carrier-added radionuclides ⁶¹Cu, ⁶²Zn, ⁶⁶Ga, ⁶⁹Ge and ⁷¹As with poly(N-vinylpyrrolidone) (PVP) were studied in multi-elemental environment by dialysis with the help of tracer packet technique. It has been observed that in acidic pH gallium has a high tendency for formation of Ga-PVP complex while the same is true for Cu and Zn in neutral and basic pH. Germanium is always inert towards the interaction with PVP at all pH values. No interaction of arsenic was observed in acidic and neutral pH; while in basic pH the tendency to form As-PVP complex is considerably higher. The result can be considered as a model of in-vivo interaction of PVP-Ga/Cu/Zn/As complexation.
