AB  - A novel quaternary ammonium salt polymer (qaps) with high adsorption sites (i.e. quaternary ammonium nitrogen confirmed by FT-IR) was designed and prepared for rapid and selective removal of Cr (VI) from water. EDS analysis 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) - IIP (46.2%). The idea of high exposure effect of adsorption sites proposed in this paper can provide valuable guidance for the design of rapid selective adsorbent to remove and recover Cr (VI) from wastewater.The high exposure effect of adsorption sites significantly improves the adsorption capacity and removal rate: Taking the adsorption of hexavalent chromium by quaternary ammonium salt polymers (qaps) as an example, the data set is obtained by experimental method. The data format is decimal (. XLS), and the data volume is 6 groups, a total of 38762 pieces.
