Experimental and Theoretical NANOTECHNOLOGY (ETN) abbreviated as Exp. Theo. NANOTECHNOLOGY is a multidisciplinary peer-reviewed and open access journal. It includes specialized research papers, short communications, reviews and selected conference papers in special issues on the characterization, synthesis, processing, structure and properties of different principles and applications of nanotechnology with focus on advantageous achievements and applications for the specialists in engineering, chemistry, physics, materials science and medicine. ETN covers and publishes all aspects of fundamental and applied researches of experimental and theoretical nanoscale technology dealing with materials synthesis, processing, nanofabrication, nanoprobes, spectroscopy, properties, biological systems, nanostructures, nanoelectronics, nano-optics, nano-mechanics, nanodevices, nanobiotechnology, nanomedicine, nanotoxicology within the scope of the journal. ETN aims to acquire the recent and outstanding researches for the benefit of the human being.
New type of nanoparticle biomass adsorbent was synthesis from Iraqi date seeds activated carbon (DSAC) and iron oxide nanoparticles (IONPs) under the optimum conditions of temperature, pH and mixture ratio of (FeCl2:DSAC). The final product was characterized for the physical and chemical properties using XRD, SEM, UV, FTIR and color test. Cadmium ion selected in this work as heavy metal; the stock solutions of Cd (II) prepared with concertation of 100 ppm. Four different initial concentrations flasks of cadmium ion prepared (25, 20, 15 and 10 ppm). The adsorption equilibrium experiments of cadmium and led onto nano adsorbent were analyzed by the Langmuir, Freundlich, and the Temkin isotherm models, the equilibrium data fitted well by the Langmuir model with maximum adsorption capacity of 15 mg/g for Cd(II).
