Magnetic Iron Oxide Nanoparticles Modified with Moringa Seed Proteins for Recovery of Precious Metal Ions

“…This further confirms the protein structure in Moringa seeds. Similar functional groups were attained for M. oleifera seed pods and Sclerocarya birrea [35] and Plantago ovata seeds [38]. On the other hand, typical functional groups for iron oxide are depicted by absorption band at 3664.7 cm −1 that corresponds to the hydroxyl functional group and a band at 543.2 cm −1 that is assigned to Fe-O (iron oxide) group [39].…”

Enhanced electrocoagulation–electroflotation for turbidity removal by Opuntia ficus indica cladode mucilage

“…Ramavandi et al . () tested a proteinous coagulant extracted from Plantago ovata seeds on a turbid water and found that at lowest coagulant dosages (0.25–0.5 mg/L) the abatement of the turbidity was reduced to 99%.…”

“…The treatment of a synthetic wastewater prepared by Kaolin by Jar test and addition of 50 mg/L of Moringa oleifera seeds, 12 and 5 mg/L of mallow and okra mucilage reduce turbidity to reach 90, 93 and 96% efficiencies, respectively (Ndabigengesere et al 1995;Anastasakis et al 2009). Ramavandi et al (2015) tested a proteinous coagulant extracted from Plantago ovata seeds on a turbid water and found that at lowest coagulant dosages (0.25-0.5 mg/L) the abatement of the turbidity was reduced to 99%. Studies suggest that mucilage of the OFI, specifically its galacturonic acid component, may be the active component that provides coagulation activity by a mechanism which functions mainly through adsorption, separately galactose and rhamnose displayed no coagulation activity (Miller et al 2008).…”

“…; Šćiban et al . ; Ramavandi ; Ramavandi et al ., ). Recently, there are many information in the literature evaluating and exploiting the advantageous use of OFI, usually known as Nopal or prickly pear, in water treatment (Miller et al .…”

“…In addition, the cost of the extraction process is low. In recent numerous studies, a variety of plant materials have been reported as a source of natural coagulants (Miller et al 2008;Sć iban et al 2009;Ramavandi 2014;Ramavandi et al, 2015). Recently, there are many information in the literature evaluating and exploiting the advantageous use of OFI, usually known as Nopal or prickly pear, in water treatment (Miller et al 2008;Torres & Carpinteyro-Urban 2012;Barka et al 2013;Bouatay & Mhenni 2014;Betatache et al 2014;Fedala et al 2015a).…”
