Abstract:
The results of investigation of active carbons, obtained from the pine waste (lat. Pínus sylvéstris) by modifying phosphoric acid and industrial (metallurgical slag) wastes, are discussed. The structure, composition and properties of obtained sorbent have been investigated by using FT-IR-spectroscopy, elemental analysis, DTA/ TGA, SEM. The iodine adsorption activity and adsorption values toward to some inorganic and organic pollutants of sorbent have been evaluated. Based on laboratory test results, it was established that the sorbent on the base of activated carbons prepared by chemical modification, followed by carbonization in the presence of metallurgical slag and water treatment, has a porous structure. It was shown that sorbent can be used in the processes of sorption concentration of phenol, chloroform, pyridine, aniline, and also heave metals ions from aqueous solutions.
