“…Cao et al [25] proposed a removal mechanism involving solid−liquid interfacial cation exchange between MgO and Pb(II) or Cd(II) to form PbO or CdO. Mahdavi et al [26] proposed MgO nanoparticles had a much greater metal adsorption capacity than TiO 2 and Al 2 O 3 nanoparticles due to the occurrence of adsorption and precipitation of heavy metal ions with MgO. Thus, an in-depth investigation into the mechanism of heavy metal ions removal using MgO nanoparticles is needed urgently.…”

“…During remediation processes, toxic contaminants are rapidly converted into significantly less toxic products (Wei et al 2013). There are various nanomaterials which can be utilized for the removal of metallic contaminants from waste water (Al-Rashdi et al 2011;Kumar et al 2014;Mahdavi et al 2013) or aquifer (Shan et al 2009), but reports on the removal of heavy metals from contaminated soil are very limited. Moreover, most of the reports describe the heavy metal removal process in laboratory scale but field scale reports are very rare.…”

Soil is an important part of environment which is under threat due to various types of contaminations happening since last few decades. Recovery and regeneration of soil have become a global problem. Recently nanotechnology has emerged as an efficient, cost effective, environment friendly and promising technology for soil remediation. This technology has significant potentiality to remove contaminants from environment by various approaches like adsorption, redox reaction, conversion, stabilization, etc. Various types of nanomaterials and devices are used to remove contaminants from soil. Therefore, soil could be remediated effectively by utilizing nanotechnology based concepts, processes and products which cannot be achieved from conventional methods. One of the most hazardous soil contaminants is heavy metal. Like other contaminants, heavy metals could be removed from soil using nanotechnology based approaches. The applications of nanotechnology to remove heavy metals from the contaminated soil are discussed in this chapter.

“…Different natural (e.g. metal oxides, bentonites, natural zeolites) and synthetic (resins, modified zeolites, synthetic hydroxides /oxides/hydroxides, metal phosphates and silicates) materials have been tested in adsorption process for removal of heavy metal from wastewater with various efficiencies [10,16]. In addition, significant research work has been done on different waste materials to improve and investigate proper sorbents for water and wastewater treatment, blast furnace slug [17,18], biomass [19,20], fly ash [21], and bagasse fly ash [22,23], among other have been investigated as sorbents for removal of heavy metal with various levels of achievement.…”

N ANO-PARTICLES, within 29-45 nano-meters, based on wollastonite were prepared with/ without CuO through wet method. The adsorption process was occurred on nano-particles powder ceramic at different conditions (pH, contact time and dose) for removing of cadmium ions from waste water. The SEM of nano-particles after treatment of waste water revealed that, surface texture of the blank adsorbents changes totally due to the adsorption of cadmium ions on the particles. At optimum operating conditions (at pH 9) cadmium ions removal reached 98.88% after measurement by ICP and EDX techniques. The obtained results showed that the produced ceramic nano-particles could be used efficiently for removal of cadmium ions with reasonable simple and low cost technique.
