Adsorption of p-nitrophenol from aqueous solution by combined membrane-adsorption technology was studied. Activated carbon samples were synthesized on the base of industrial by products (coal tar pitch) and biomass. Synthetic activated carbon synthesized from mixture of coal tar pitch and furfural by thermo-oxidation treatment with sulfuric acid at 200oC, and subsequent carbonization in nitrogen atmosphere at 600 oC, followed by hydro-carbonyzation at 800oC. Biomass based activated carbon was obtained by hydro-car...

With clastic sedimentary rocks associated deposits of ore, oil-and-gas, coal and non-metallic minerals. They are located in a variety of different age strata structural-tectonic stages. Sedimentary rocks composing these fields are often framework rocks or minerals themselves are economic minerals. Depending on the age and affinity to specific structural and tectonic tier breeds are in various stages of the penecontemporaneous transformation. By the degree of transformation of organic matter in the clastic rocks ca...
