In this paper, we investigated the superiotires of carbon-based nanomaterial polymer inclusion membrane (PIM-GO) against to polymer inclusion membrane and removed Cr(VI), a highly toxic element typically used in chromate conversion coating in the plating industry, from the chrome plating water by using a PIM-GO modified with graphene oxide (GO), which strengthens the mechanical structure and permeability of PIMs. We performed experiments to investigate the membrance performance and structural ability ofthe PIM-GO, and lastly compared its performance to that of the PIM. We observed the PIM-GO’s high selectivity and recovery (96.83%) in the removal of Cr(VI). GO added to the membrane structure caused a visible increase in the rate constant, permeability and flux.The PIM-GO affords opportunities to work with a wider range of pH levels, changes of which in membrane-based experiments with unmodified PIM shave caused significant decreases in flux and permeability. The ease of use, app...

纳米材料改性聚合物膜在温度和机械稳定性方面的优势及其在工业废水中的应用

在本文中,我们研究了碳基纳米材料聚合物夹杂膜(PIM-GO)相对于聚合物夹杂膜的优越性,并从中去除了铬(VI),一种通常用于电镀行业铬酸盐转化膜中的高毒性元素。通过使用氧化石墨烯(GO)改性的PIM-GO镀铬水,可增强PIM的机械结构和渗透性。我们进行了实验以研究PIM-GO的膜性能和结构性能,最后将其性能与PIM进行了比较。我们观察到PIM-GO在去除Cr(VI)时具有很高的选择性和回收率(96.83%)。添加到膜结构中的GO引起速率常数,渗透性和通量的明显增加。PIM-GO提供了在更宽的pH值范围内工作的机会,在未经修饰的PIM剃须的基于膜的实验中,这些改变导致通量和渗透率显着降低。易用性,应用程序...
