Abstract: The study of permeability of 137Cs, 90Sr and 60Co from nitrate media was carried out using Nanocomposite hydroxy apatite/activated carbon. The efficiency of this extractant was studied under various experimental conditions, such as aqueous pH,NaNO3M present in the initial aqueous feed , Nanocomposite hydroxy apatite as carrier in the membrane disc ,EDTA as stripping phase concentration, temperature and time of extraction were studied The percentage of 137Cs, 90Sr and 60Co extraction decreases with the increase of temperature at varying concentration of Nanocomposite hydroxy apatite. The pertraction of 137Cs, 90Sr and 60Co from nitrate media were examined at the optimized conditions. Under the optimum experimental conditions 98.6–99.9% of 137Cs was extracted in 10–30 min with the initial feed concentration of 0.5 NaNO3 This Study was developed using a new nanohydroxyapatite–Activated carbon. The nanohydroxyapatite (nHAP) particles mixed with Activated Carbon (AC) acts as the inorganic phase was mixed with activated carbon (AC) forming HAp-AC composite. Facilitated transport supported liquid membranes (SLMs) were prepared at 20oC temperature. Recently novel compositions in this system HAp-AC were described and characterized with regard to DTA,SEM, IR ,surface investigated and spectra. The process of diffusion in liquid membranes is governed by chemical diffusion process .Fick’s first law of diffusion.
