Adsorption of heavy metal ions (Cu(2+), Ni(2+), Co(2+) and Fe(2+)) from aqueous solutions by natural zeolite
The process of remove copper, nickel, cobalt and iron ions by natural zeolite of the Yagodninsky deposits, Kamchatka region, from water resources within a concentration range of 0.5–3.5 mg-eq/L has been experimentally investigated. The specified concentrations range was chosen according the contents...

The process of remove copper, nickel, cobalt and iron ions by natural zeolite of the Yagodninsky deposits, Kamchatka region, from water resources within a concentration range of 0.5–3.5 mg-eq/L has been experimentally investigated. The specified concentrations range was chosen according the contents of heavy metals in the waste water of the mining enterprise of Kamchatka region The values of maximum sorption capacity have been determined. On the basis of studies using X-ray powder diffraction (XRD) it has been established by the Rietveld method of calculation that the zeolite tuff of the Yagodninsky deposit consists of clinoptilolite-Na (23.0 %), clinoptilolite-Ca (52.1 %) and modernite (12.9 %). It has been established that exchange cations are sodium, calcium, potassium and magnesium. The Gibbs free energy has been calculated which is equal for copper ΔG = –25.6 kJ/mol, iron – ΔG = –23.7 kJ/mol, nickel – ΔG = –21.5 kJ/mol and cobalt – ΔG = –20.0 kJ/mol. The obtained results show that natural zeolite can be used as an effective sorbent for extracting of ions Cu(2+), Ni(2+), Co(2+) and Fe(2+) from polluted waters.
