Fabrication and Characterization of SiO2/(3-Aminopropyl)triethoxysilane-Coated Magnetite Nanoparticles for Lead(II) Removal from Aqueous Solution

Removal of bisphenol A and some heavy metal ions by polydivinylbenzene magnetic latex particles

“…The results showed that the adsorbed amount of BPA, Cu 2+ , Pb 2+ , and Zn 2+ increased rapidly with increasing MP DVB amount and reached a maximum at 4 and 2 mg for the heavy metals and the bisphenol A, respectively, then decreased with further increasing of MP DVB amount. This phenomenon was reported by other authors (Gong et al 2012, Mahdavi et al 2013, Feng et al 2010). The increase trend in Fig.…”

“…An optimum adsorbent dose is essentially required to maximize the interactions between pollutants and adsorption sites of adsorbent in the solution (Hao et al 2010;Feng et al 2010, Mahdavi et al 2013. To evaluate the optimum dosage of MP DVB adsorbent, 0.5-10 mg of prepared MP DVB was added to 4 mL of aqueous solution containing 200 mg L −1 Cu 2+ , Pb 2+ , and Zn 2+ (2 mL of aqueous solution containing 250 mg L −1 BPA).…”

“…The increase trend in Fig. 6 Effect of MP DVB amount on the BPA, Cu 2+ , Pb 2+ , and Zn 2+ removal the first stage is rather difficult to explain; some author nonetheless explain that by the increase of the number of available adsorption sites with the increase of adsorbent dose (Mahdavi et al 2013, Feng et al 2010. The decrease observed of sorbent capacity may be due to insufficiency of metal ions in solution with respect to available binding sites.…”

A Review of Current Research into the Biogenic Synthesis of Metal and Metal Oxide Nanoparticles via Marine Algae and Seagrasses

“…These unique and novel size-dependent properties have led to nanoparticles being promoted for a wide range of applications. Typical applications include biosensors [7,8], catalysts [9][10][11], environmental remediation [12][13][14], labelling for immunoassays [15,16], hyperthermia treatment of tumors [17][18][19], antibacterial drugs [20,21], and vector delivery of therapeutic drugs for cancer treatments [22][23][24]. However, studies have also shown the properties of manufactured nanoparticles are heavily dependent on specific parameters such as particle size, morphology, and size distribution [25].…”

A Facile Plant Mediated Synthesis of Magnetite Nanoparticles Using Aqueous Leaf Extract of Ficus Hispida L. for Adsorption of Organic Dye

“…During the past two decades metal oxide nanomaterials have attracted a great attention due to their unique optical, electrical, magnetic and electronic properties [1].Especially, the magnetic metal oxide nanoparticles received much attention for a wide range of applications such as catalysis, biosensors, ferrofluids, high density magnetic storage media, separation and purification of biomolecules [2][3][4][5][6]. Among all magnetic metal oxides, magnetite (Fe 3 O 4 ) have emerged potential candidates for advance technological applications due to their low toxicity, biocompatibility and super paramagnetic behaviour [7][8][9].…”
