本文设计并制备了一种新型的高吸附位点(即经FT-IR证实的季铵化氮)的季铵盐聚合物(QAPs)，用于快速选择性去除水中Cr(VI)。EDS分析结果表明，氮在QAPs表面的最大暴露率高达86.1%，几乎是Cr(VI)离子印迹聚合物(Cr(VI)-IIP)(46.2%)的两倍。本文提出的吸附位点高暴露效应的思路可为设计快速选择性吸附剂去除和回收废水中的Cr(VI)提供有价值的指导。\n

This article designs and prepares a novel quaternary ammonium salt polymer (QAPs) with high adsorption sites (i.e., quaternized nitrogen confirmed by FT-IR) for rapid and selective removal of Cr (VI) from water. The EDS analysis results showed that the maximum exposure rate of nitrogen on the surface of QAPs was as high as 86.1%, almost twice that of Cr (VI) ion imprinted polymer (Cr (VI) - IIP) (46.2%). The idea of high exposure effect of adsorption sites proposed in this article can provide valuable guidance for designing rapid selective adsorbents to remove and recover Cr (VI) from wastewater.\n
\nThe high exposure effect of adsorption sites significantly improves adsorption capacity and removal efficiency: taking the adsorption of hexavalent chromium by quaternary ammonium salt polymers (QAPs) as an example dataset, the data was obtained using experimental methods in decimal (. xls) format, with a data volume of 6 groups and a total of 38762 entries.
