GREEN SYNTHESIS OF NANO-FE–BIOTITE FOR REMOVAL OF HAZARDOUS METALS IONS FROM AQUEOUS SOLUTIONS

Khaled M. Elsabawy*, Morsy M.A.Sekkina and Ahmed T.Tawfik.

Abstract
This paper represents synthesis of a new family of a fluoride-free Fe-Biotite type compound having the general formula
NaFe2.5(Al,Si)4O10 (OH)2. It was prepared carefully by using solid- state reaction technique with nominal compositions of
individual oxides in the main formula for the potential remediation of heavy metals and some radioactive elements from
applying solution. The structural and micro-structural properties were determined using both XRD, SEM and IR techniques.
The particle size estimated was 56 nm. Further electron spin resonance (ESR) proved that Fe-biotite is paramagnetic in
nature, electrical conductivity was measured as a function of absolute temperature, while the thermal stability of the samples
were studied using thermogravimetry (TG). Analytical applications were done by using (AAS). Investigations proved that
synthetic fluoride-free Fe-biotite has medium of strong efficiency as cation selective clay towards metals under test.

Key words: biotite, heavy metals, uranium, thorium, removal, fluoride-free , wastewater
