“…Researchers have proposed different physical and chemical approaches, such as chemical sensors coagulation, reverse osmosis, precipitation, adsorption, filtration, and bio‐remediation, to reach the maximum capacity of cadmium uptake from environmental samples. The simplest, most inexpensive, highly efficiency, and low‐cost method is the adsorption process .Researchers have focused in the adsorption of toxic metals by metal oxide nanoparticles (NPs), such as iron, silver, carboxylate, graphene oxide and ferrocene, . Iron metals in sub‐micrometer particles are called zero‐valent iron NPs (α‐Fe) and have a large surface area and high surface reactivity .…”

We report the one‐pot synthesis of ball‐like nanosphere structures composed of an α‐Fe core and an organic shell of ethylenediaminetetraacetic acid that connected together to form a nanochain necklace‐like morphology. The hierarchical zigzag nanochain sphere structures have branches growing in clumps, a large surface area, and spherical pore‐like cages and entrances for capture/trapping Cd2+ ions from water sources. The pH solution (i.e., at pH 5) plays a key role in the generation of actively negative surfaces along the entire nanochain sphere adsorbent, thereby creating surfaces with strong binding affinity to Cd2+ ions. The thermodynamic and kinetic characteristics indicated that the nanochain sphere adsorbent with macro‐ and meso‐cage caves and organically decorated surfaces show promise for the spontaneous and endothermic capturing of Cd2+ ion containments from water solutions. The zigzag nanochain mesoporous necklace‐like structure trapper (MNT) exhibited long‐term stability, indicating that it can be used several times (reduced waste volume). The adsorption efficiency and uptake of the deleterious Cd2+ ions retained even after multi‐particulate processing of reuse cycles. The pH‐dependent Cd2+ ion selectivity indicated high adsorption capacity (526.3 mg⋅g−1) and Cd2+ ion‐to‐MNT binding affinity, despite the addition of interfering cations or anions. The zigzag nanochain sphere necklace allows the development of a simple and effective adsorbent model for water purification and management of toxins.

“…In addition, iron oxide surfaces in many other studies were functionalized with suitable functional groups aimed at improving their selectivity towards targeted pollutants. Lauric acid, oleic acid, L-arginine, ethylenediaminetetraacetic acid, sulfo (SO 3 H), maleate, humic acid (HA), polyrhodamine and 2-mercapto benzothiazole-capped iron oxide nanoparticles have been used for the removal of Cd 2+ , Pb 2+ and Hg 2+ from aqueous solution [78,88,110,119,120]. These functionalized iron oxides afforded an adsorption capacity range of 0.59-108.93 mg g −1 .…”

Heavy metal pollution and the role of inorganic nanomaterials in environmental remediation

Contamination of water and soil with toxic heavy metals is a major threat to human health. Although extensive work has been performed on reporting heavy metal pollutions globally, there are limited review articles on addressing this pernicious phenomenon. This paper reviews inorganic nanoparticles and provides a framework for their qualities required as good nanoadsorbents for efficient removal of heavy metals from water. Different inorganic nanoparticles including metals, metal oxides and metal sulfides nanoparticles have been applied as nanoadsorbents to successfully treat water with high contaminations of heavy metals at concentrations greater than 100 mg l −1 , achieving high adsorption capacities up to 3449 mg g −1 . It has been identified that the synthesis method, selectivity, stability, regeneration and reusability, and adsorbent separation from solution are critical parameters in deciding on the quality of inorganic nanoadsorbents. Surface functionalized nanoadsorbents were found to possess high selectivity and capacity for heavy metals removal from water even at a very low adsorbent dosage of less than 2 g l −1 , which makes them better than conventional adsorbents in environmental remediation.

“…Experimental design is an efficient method to study the parameter effects and optimize various variables for obtaining the best results by fewer experiments. The Taguchi method is a well-known and fast technique that can be used for experimental design and response optimization (Montgomery 2017;Moattari et al 2015). In this work, the effects of all the important parameters including type of metal ions, reagent ratio, time and temperature of synthesis were studied and optimized by the Taguchi method.…”

In this work, MIL-101, a metal organic framework, has been synthesized and examined in the adsorptive denitrogenation process. Due to the importance of adsorption capacity and selectivity, the effects of synthesis parameters including metal type, reagent ratio, time and temperature on the MIL-101 performance were investigated by measuring quinoline (QUI) separation from iso-octane. The optimum conditions were determined using a Taguchi experimental design and the multiresponse optimization (multivariate statistical) method. Based on the arithmetic mean of normalized QUI adsorption capacity and QUI/dibenzothiophene (DBT) selectivity, as the objective function, the optimum value of synthesis parameters were found to be manganese as metal type in the structure, 180 °C for synthesis temperature, 15 h for synthesis time and 1.00 for reagent molar ratio. Under these conditions, QUI adsorption capacity and QUI/DBT selectivity were 19.3 mg-N/g-Ads. and 24.6, respectively. Accordingly, the arithmetic mean between normalized values of these measured parameters was equal to 1.10, which is in good agreement with the predicted value. The MIL-101 produced under optimum conditions was characterized by determining its specific surface area, X-ray powder diffraction patterns and Fourier transform infrared spectroscopy. Finally, isotherm and kinetic studies indicate that the Langmuir isotherm and pseudo-first-order model can successfully describe the experimental data.
