纳米银在不同盐溶液中的溶解

Dissolution of Silver Nanoparticles in Salt Solutions

对纳米银在含有不同盐溶液中的物理化学特性进行研究;考察了不同离子对纳米银的溶解动力学的影响,采用ICP-MS对纳米银在不同盐溶液中的溶解进行了研究;结果表明,纳米银颗粒的溶解随天然盐含量的增加而减小。本研究对揭示纳米银在自然水体中的迁移有重要指导意义。

The study investigated the dissolution kinetics of silver nanoparticles in presence of different salt solutions. ICP-MS was used to quantify the silver nanoparticle dissolution in presence of salt solutions. The obtained results suggested that the dissolution rate of silver nanoparticles decreases with increasing salt concentration. Our study provides important guidance in elucidating the transport and fate of silver nanoparticles in natural water conditions.
