摘要：
This study evaluates the effect of water condition on the physicochemical properties of silver nanoparticles (AgNPs) with/without capping agent. The results show that the average particle size of AgNPs increases with increasing in electrolyte concentration. Divalent cation (Ca2+) can more effectively increase the size and zeta-potential of AgNP aggregates than monovalent cation (Na+). This study also indicates that PVP, humic acid or natural organic matters can increase the stability of AgNP suspension. Larger AgNPs aggregates are formed in seawater than in lake water.
