The mesoporous melamine−formaldehyde resin was synthesized in the process of polymerization in the
presence of fumed silica as an inorganic template. To differentiate the surface properties, the polymer
sample was modified by applying 2-methyl-1-butanol. The surface and structural characteristics of obtained
sorbents were investigated using various techniques: XPS, SAXS, and sorption from gas phase. The
porous structure of initial and modified melamine−formaldehyde resins was determined from nitrogen
adsorption/desorption isotherms. To study the polymer activity toward organic substances dissolved in
water, the isotherms of sorption of organics from aqueous phase were measured for a wide range of solution
concentrations. The liquid sorption data were analyzed to study the effect of polymer structure and surface
properties on sorption processes.
