Summary:
Wastewater treatment from the copper ions (II) is a serious problem galvanic production. This is due to both high toxicity of the element, and low concentrations established for disposal. Agricultural wastes can serve as raw material for production of sorbents that can solve such environmental problems as the disposal of plant wastes and wastewater treatment. In this study the sorption properties of carbon materials PU-1 and PU-2 obtained from plant wastes (buckwheat husks and sunflower, respectively), and activated carbon AN-K4 produced from anthracite, with respect to the ions of copper (II) were investigated.
From the studied samples maximum surface area and therefore the best sorption properties had activated carbon AN-K4. The maximum sorption was observed in the pH interval 7.5-8 (for UE-1 and AN-K4) and pH 7-9 (for PU-2). Isotherms of sorption of copper (II) in all the studied samples belong to the Langmuir type. Increasing the degree of sorption in the pH interval from 3 to 6, as well as reducing the sorption capacity of the sorbent resulting from the acid treatment allows to conclude that a significant contribution to the mechanism of sorption of copper (II) a process with participation of chemisorption of carboxyl groups.
Because of studying the effect of the contact time of the phases on the rate of attainment of equilibrium it was shown that in the studied samples sorption occurs quite rapidly and almost complete after 3 minutes.
The possibility of the use the studied samples for additional treatment of galvanic production waste water from ions of copper (II) was shown. The highest recovery rate is typical for AN-K4. From the sorbents derived from processing wastes of plant raw material, the most promising for wastewater treatment is PU-2.
