在水的 nanocrystals (NC ) 的传统的 2-propanol-based 纯化期间,从水的解决方案再循环 2-propanol 是很困难的,它在纯化进程期间带 2-propanol 的大消费。这个工作的主要贡献是提供一个简单方法经由在纯化过程期间 2-propanol 再循环减少消费。再循环的 2-propanol 是可得到的因为从在 NC 纯化的一个新回合的水的答案的猛抛的 NC 处理。由于再循环 2-propanol, 2-propanol 的大消费能被避免,它做绿得多的水的 NC 并且以低得多的成本的纯化过程。
During traditional 2-propanol-based purification of aqueous nanocrystals (NCs), it is very difficult to recycle 2-propanol from the aqueous solution, which brings great consumption of 2-propanol during the purification process. A major contribution of this work is to provide a simple way to reduce the consumption via recycling of 2-propanol during the purification process. The recycled 2-propanol is available for precipitating NCs from aqueous solution in a new round of NC purification process. Due to the recycling of 2-propanol, the great consumption of 2-propanol can be avoided, which makes the purification process of aqueous NCs much greener and at a much lower cost.
