The Plasma-Induced Formation of PVP-Coated Silver Nanoparticles and Usage in Water Purification
The contact non-equilibrium low-temperature plasma technique is used to synthesize silver nanoparticles (AgNPs) employing polyvinyl pyrrolidone (PVP) as a capping agent. Influences of PVP concentration on the formation efficiency of silver nanoparticle, their average size and stability have been studied. The synthesized silver nanoparticles had a significant antibacterial activity against two strains of Gram bacteria. Silver nanoparticles (AgNPs)-alginate composite beads with different PVP concentration were synthesized as materials for water purification.
