Biosynthesis of Multicomponent Nanoparticles with Extract of Mortiño (Vaccinium floribundum Kunth) Berry: Application on Heavy Metals Removal from Water and Immobilization in Soils

Abstract

rough preparation of multicomponent nanoparticles (MCNPs) using ferric chloride (FeCl 3 ), sodium sulfate (Na 2 SO 4 ), and the extract of mortiño fruit (Vaccinium floribundum Kunth), we dramatically improved the removal/immobilization of heavy metals from water and in soils. As-prepared nanoparticles were spherical measuring approximately 12 nm in diameter and contained iron oxides and iron sulfides in the crystal structure. Removal of copper and zinc from water using MCNPs showed high efficiencies (>99%) at pH above 6 and a ratio of 0.5 mL of the extract:10 mL 0.5 M FeCl 3 ·6H 2 O : 10 mL 0.035 M Na 2 SO 4 . e physisorption process followed by chemisorption was regarded as the removal mechanism of Cu and Zn from water. While, when MCNPs were used to treat soils contaminated with heavy metals, more than 95% of immobilization was accomplished for all metals. Nevertheless, the distribution of the metallic elements changed in the soil fractions after treatment. Results indicate that immobilization of metals after the injection of nanoparticles into soils was effective. Metals did not leach out when soils were drained with rain, drinking, and deionized water but fairly leached out under acidic water drainage.

Green Synthesis of Iron Nanoparticles: Application on the Removal of Petroleum Oil from Contaminated Water and Soils

“…As seen in Figure 4(a) and Table 2, peaks in the range of 3650-3200 cm −1 are related to the vibrations of the −OH groups of the phenolic moiety of mortiño berry extract, positions from 1620 to 1690 cm −1 are attributed to the aldehydes (C O) of an ester sugar [27]. ese peaks in conjunction with the 1089 cm −1 peak (CO stretching) represent the amount of carbon that belongs to the extract [28]. Conversely, for the nanoparticles, peaks of C C alkene conjugate cis and benzene ring 1634.98 cm −1 can be seen [23].…”

Retention of heavy metals from mine tailings using Technosols prepared with native soils and nanoparticles

“…Hence, chemical adsorption plays an important role on the heavy metals’ adsorption using Technosols. In previous research, it has been demonstrated that chemisorption of heavy metals is quite permanent and no leakage has been observed in leachate tests using multicomponent nanoparticles and soils with different aqueous extractants ( Abril et al., 2018 ). The best correlation for all of the kinetic systems studied, is the pseudo-second order model.…”

The potential of nanoparticles synthesized by green route, for its application in the remediation of contaminated soils

“…La aplicación de NP Fe obtenidas de extracto de bayas de Mortiño, para la inmovilización de metales pesados como Cu, Ni, Zn, Mn, Cr, Cd; tiene un resultado con un 99% de eficiencia en remoción, así mismo, demuestra que estos metales presentes en el suelo no se filtran incluso cuando fluye agua de lluvia, agua potable y agua desionizada a través del suelo. Sin embargo, la lixiviación de metales pesados es moderada cuando se usa agua ácida como solución extractora [15].…”
