An investigation of the interaction between polyvinylpyrrolidone and metal cations

Structural and Optical Properties of Li<sup>+</sup>: PVP & Ag<sup>+</sup>: PVP Polymer Films

“…: PVP polymer films. This is in good agreement with the size distribution measurement of pure-PVP and Li + PVP aggregates [14]. PVP is a hydrophobic polymer which has an affinity towards the Ag + ion silver in the formation of covalent bond between pyridyl groups and silver ion.…”

Fabrication of Nickel Nanosized Powder from LiNiO2 from Spent Lithium-Ion Battery

“…When a liquid sample is irradiated with ultrasonic waves, a vibrating plate is generated to bring strong energy, thereby dispersing the agglomerated fine particles [10]. In order to prevent the agglomeration of the dispersed particles, PVP was added to the solvent to coat the nanosized nickel powder to stabilize the dispersed particles to minimize agglomeration [11,12]. Ultrasonic intensity was fixed at 40 kHz, and ultrasonic dispersion was performed at 10 • C for 120 min.…”

Kinetic Study of Chromium (III) - PVP Complex by using Radio-Tracer Technique

“…PVP forms complexes with metals via oxygen and nitrogen donor sites, due to the high polarity of the lactum ring conferred by resonance stabilisation facilitated by a near planer geometry. The interaction between PVP and some metal ions was also investigated by Liu et.al, 2000 [5]. They studied the complexation of the metal cations like Fe 3+ , Co 2+ and Ni 2+ with PVP in ethanol and water and reported the formation of complexes with the help of UV-Vis and IR spectroscopy.…”

“…When these compounds are used in nuclear medicine of radio-pharmacy it is indispensable that the metal complexes stay intact (Li et.al. 2000 [5]) during transport to the desired location, which means a they should neither be metabolized nor should the complexed metal ion get lost because of insufficient stability of the metal complex.…”
