Extraction of Iron Ions (II) from Aqueous Solutions with Carbonic Sorbents
SUMMARY
The absorbing capacity of carbonic sorbents of ИПИ-Т mark regarding iron ions (II) has been studied. Sorbents on the basis of carbonated polymer materials stable to aggressive media, have a developed specific surface area, inexpensive. Isotherms of adsorption under static conditions at temperature of 298 K have been obtained. The isotherm of adsorption is described satisfactorily by the Langmuir equation. Results of the study shows that carbonic sorbents of ИПИ-Т mark are able to sorb iron ions (II), in the process, a sorption capacity is 0,24 mole/g. The kinetics of the process has been studied, thermodynamic parameters of sorption have been determined. The sorption method of treatment with the use of sorbents of ИПИ-Т can be economically sound. Сarbonic sorbents are perspective for selective extraction of iron ions (II) from industrial wastewater.
