Preparation of sorbents from selected polymers In this work, the results of studies on the preparation of sorbents from selected polymers were presented. The polymers were carbonized and subsequently physically activated by steam or carbon dioxide, or alternatively, chemically activated with potassium hydroxide. For the obtained materials, a specific area was evaluated by means of low-temperature nitrogen adsorption and benzene adsorption, iodine number was also determined. The obtained results indicated a possibility to procure hydrophobic sorbents of microporous structure. Sorbents having the best properties, i.e. the specific area of above 2000 m2/g were produced from poly(ethylene terephthalate) and phenol-formaldehyde resin.

Abstract The last comprehensive review of tire-cord adhesion to rubber was reported by T. Takeyama and J. Matsui in Rubber Reviews for 1969. They covered this subject in depth from its scientific beginnings and dealt mostly with rayon, nylon, and polyester tire-cord adhesion. The objective of this present review will be to up-date the 1969 review. The resorcinol-formaldehyde-latex (RFL) adhesive system developed as a fiber adhesive in the early 1940's is still in use throughout the rubber industry at the present time. No other resin has replaced the resorcinol-formaldehyde resin and no other latex has replaced 2-vinylpyridine-butadiene-styrene latex as components in adhesive dip recipes. This will probably be true into the foreseeable future. There was really no need to improve the adhesion of rayon and nylon to rubber, so very little development work was done with the adhesion of these two fibers. However, a considerable amount of work was done with polyester adhesion and this coincided with the expanded use of poly(ethylene terephthalate) fibers in passenger tires. Much of this effort was concerned with single-step adhesive dips where the adhesion activating ingredients were added to a standard RFL mixture.

Abstract An eco-friendly method for the synthesis of granular activated carbon was developed in this study. Two types of activated carbon and three types of activated carbon granules have been obtained using different binders, and their properties have been determined. The approach requires adding other binders and waste materials to improve the granulation of activated carbon. Activated carbon was prepared from birch wood chips. Prepared carbon was granulated with a) gas generator tar, b) phenol-formaldehyde resin, and c) polyvinyl acetate to obtain granular activated carbon. This work aims to study the possibilities of using activated carbon adsorbents for CO2 adsorption. The activated carbon produced was characterized by BET, FTIR, and SEM. The adsorption behavior on CO2 was also studied. Granular activated carbons compression strength was enough to study it in an adsorption bed, and an optimal binder was to be phenol-formaldehyde resin and polyvinyl acetate. The obtained results show that activated carbon granules are suitable for CO2 adsorption and can be used, for example, for the removal of CO2 in the biogas upgrading process. As the sustainability problems are increasing, granules from waste materials could be promising materials for further studies.

The paper evaluates the effectiveness of the use of graphene nanostructures in the purification of lead (II) ions to improve the ecological situation of water bodies. The mechanisms and characteristic parameters of the adsorption process were analyzed using empirical models of isotherms at temperatures of 298, 303, 313 and 323 K, which correspond to the following order (based on the correlation coefficient): Langmuir (0.99) > Temkin (0.97) > Dubinin – Radushkevich (0.90). The maximum adsorption capacity of the material corresponds to the range from 230 to 260 mg/g. We research the equilibrium at the level of thermodynamic parameter estimates, which indicates the spontaneity of the process, the endothermic nature and structure change of graphene modified with phenol-formaldehyde resin during the adsorption of lead (II) ions, leading to an increase in the disorder of the system.
