Using the Taguchi method, extraction of 1,10−Phenanthroline and 2,2'-Bipyridine from aqueous samples by solid phase extraction system has beenstudied. The extraction is based on a new nanoporous CMK-1 modified with sodium dodecyl sulfate and Fe+3. The structural and textural properties of modifiedsorbent were studied by X-ray diffraction, nitrogen adsorption isotherm, scanning electron microscopy and FT-IR technique. The 1, 10-Phenanthroline and 2,2'-Bipyridine were selectively adsorbed on this sorbent and subsequently, were recovered with dimethyl sulfoxideand the extractions efficiencies were measured by UVVisinstrument. The controllable factors such as pH, solution speed, sorbent mass, eluent volume and elutionspeed have been optimized applying the Taguchi method. The results have showed that dynamic linear range exhibited a good linearity between 20 and 600 μgL−1. The limits of detection for 1,10-Phenanthroline and 2,2'-Bipyridine were 8.75 and 10.1 μg L-1 respectivelyand the extraction efficiencies were above 93% in optimum conditions. Finally, this method was successfully applied for determination of thesecompounds in real samples. The various optical properties of these nanoporous such as band gap, refractive index and dielectric constants have been analyzed by using UV-Vis data.
