      Abstract:

      Lead toxicity became a major concern worldwide and it is one of   the most harmful pollutants in soil and groundwater. Hence, to   remove lead from the soil, a high efficient technology with   improved materials and system is required. This paper is a study   shows removing of lead ions from soil samples, which have been   taken from different sites in the Kurdistan Region, and   investigated the adsorption of lead ions on high efficient   adsorbent Fe3O4 nanoparticles. The magnetite nanoparticles of   27nm were synthesized by using a co-precipitation method and   characterized by X-ray diffraction (XRD), Fourier Transform   Infrared Spectroscopy (FTIR) and scanning electron microscopy   (SEM) equipped with energy dispersive X-ray spectroscopy (EDX).   The adsorption experiments occurred at pH 8.0 under room   temperature (25 °C) and the adsorption capacity was 22.8 mg/g   which is 4 times higher than that of coarse particles. The   correlation is measured between pH and absorbance, pH and   concentration, electrical conductivity and concentration of lead   ions in agricultural soil. These relationships indicate that the   correlation coefficient values of (r = - 0.68, – 0.70 and + 0.83)   are statistically significant at (ɑ= 0.05). The limit of   detection (LOD) and limit of quantification (LOQ) were found to   be 0.73 mg/L and 2.44 mg/L, respectively.
