“…On the other hand, there are many works indicating lack of correlation between the value of specific surface area and ability to adsorb phenols [16,24,25,27,33,41]. However, specific surface area is still put into characteristic in order to define the morphology of the adsorbent and for comparative purposes.…”

Sorption of phenolic compounds is a very complex process and many factors influence it. At the beginning, detailed chemical structure of phenols is presented with its consequence for physical properties, for example, values of melting and boiling points, solubility in water, pKa and Log P. Also influence of activating and deactivating substituents on the properties is explained. On this basis, interaction with the most frequently used sorbents, for example, chemically modified silicas, polymers and porous carbons, is described. Both sorbents characteristics including physical (porosity) and chemical properties (functional groups) and experimental conditions such as concentration of solutes, contact time, temperature, solvent effects and presence or absence of oxygen are taken into account. The explanations of irreversible adsorption and oxidative coupling phenomena are included. The mechanisms of phenolic compounds sorption are described.

The synthesis and characterization of luminescent hybrid composites based on bisphenol A glycerolate (1 glycerol/phenol) diacrylate (BPA-Acr) as a cross-linking monomer and N-vinylpyrrolidone (NVP) as an active diluent, in the presence of UV initiator (Irgacure 651), are presented. Eu(III) and Tb(III) carboxylate complexes were added as luminescent components of composites. In their preparation, a constant concentration of the initiator (1%) and the BPA-Acr to NVP (10:3) ratio were applied. The structures of the obtained materials were confirmed by the infrared spectra (ATR-FTIR). Thermal properties of the cross-linked products were determined by different thermal analysis methods in air and nitrogen (TG-DTG-DSC and TG-FTIR). Thermal stability, pathways of thermal decomposition and volatile products of degradation were determined. Photoluminescence properties of the lanthanide complexes and the obtained composites were established. These materials can have the potential application as coatings filtering harmful UV radiation.

“…The interactions of the other phenols with the polymer surface is not so strong, therefore their recoveries are lower. As our previous studies proved [30], the adsorbents possessing pores with width 3-4 nm were the most effective in the sorption of phenols. The materials presented in this work have also pores in this range, but their contents in the structure is probably insufficient to provide higher sorption capacity.…”

Highly cross-linked polymers are commonly used in purification and separation techniques because of their many useful features. In order to better adjust their porosity to adsorption of specific compounds, methods like surface functionalization or imprinting are used. In this work, a series of highly cross-linked polydivinylbenzenes (pDVB) were prepared using a suspension method. Toluene was applied as a pore-forming diluent. Some part of toluene (1 mL) was replaced with phenol (F), 2,4,6-trichlorophenol (T) or their mixture (M) to prepare polymers with porosity more suitable for phenols sorption. Another approach was an introduction of sulfone groups onto the polymer surface (pDVB-SO3H). The physicochemical characteristics of the synthetized adsorbents included CHN, FTIR, DSC and porosimetric analyses. Afterwards, to evaluate sorption properties of the prepared adsorbents towards phenols, ibuprofen and salicylic acid the solid phase extraction (SPE) experiments were performed. The polymers had the specific surface areas of about 440–560 m2/g created mainly by mesopores with widths ca. 3.75 and 4.75–7.15 nm. Materials obtained with the addition of porosity modifiers (phenol, trichlorophenol, mixture) had more uniform porous structure and their sorption capacity toward phenols increased ca. 5%. Similar sorption capacities were obtained for ibuprofen. Salicylic acid had low affinity to the surface of the tested polymers.
