摘要: Abstract Environmental boron removal and salt lake brine enrichment are important separation processes, which of great significance to animal plant health, environmental safety, effective use resources. Polymers often used for due their low cost high performance. In this study, Tris(hydroxymethyl)methyl aminomethane (TRIS) glucose functionalized polymer (P(GMA-co-TRIM)) were synthesized by hydrothermal method, the structure characterized FTIR, SEM, Mapping, XRD, XPS, PZC TG-DSC-DTG. P(GMA-co-TRIM)-TRIS P(GMA-co-TRIM)-Glu as adsorbents performance test carried out. When pH = 8 solution, two have best adsorption performance, with capacity 16.25 18.09 mg/g, respectively. The effects initial concentration contact time on studied. Langmuir isothermal model pseudo-second-order more consistent data, process was chemical adsorption. strong resistance ion interference cycle life, potential application value in extraction from lake.
