Copper oxide nanoparticles (CuO NPs) were synthesized in air by reducing copper (II) sulfate pentahydrate salt (CuSO₄·5H₂O) the presence of sodium borohydride. The reaction was stabilized with Hexadecyltrimethylammonium bromide (CTAB) a basic medium and using ultrasound waves. Different molar ratios CTAB:Cu2+ NaBH₄:Cu2+ explored, to optimize synthesis conditions, study stability, size, Zeta potential colloidal suspension. Optimum conditions generate spherical, stable, monodispersed...
Mining is an economically-beneficial activity recognized as crucial in modern society since almost every aspect of our lives relies on minerals. However, intensive mining activities impose a severe strain the water-energy nexus. In fact, ventures: i) need massive amount water various ore processing steps; ii) generate huge waste (tailings), generally transferred to tailing ponds or dams, that are potential source contamination and adverse ecological effects; iii) energy-intensive practices...
Metal chelators and porous sorbents are two of the forefront technologies applied for recovery separation hazardous and/or valuable metal ions from aqueous solutions (i.e., polluted water sources, metal-rich mining wastewaters, acid leachates, so forth). The transfer coordination functions to chemically stable host materials had only limited success far. Here, we report installation natural acids malic acid, mercaptosuccinic succinic fumaric citric acid) amino histidine, cysteine,...
This work proposes an innovative integration of Membrane Distillation (MD) and photo-oxidation for a continuous recovery water from arsenic (As) contaminated solutions coupled with the oxidation arsenite (As(III)) into arsenate (As(V)). Polyvinylidene fluoride (PVDF) mixed matrix membranes (MMMs) containing titanium dioxide nanoparticles (TiO2 NPs) as photocatalyst were developed. A systematic study elucidated effect TiO2 NPs on membranes' morphology prepared via non-solvent-induced phase...
Abstract Despite rapid technological progress, heavy metal water pollution, and particularly arsenic contamination, remains a significant global challenge. In addition, the stabilization of trivalent as neutral arsenite (As III ) species hinders its removal by conventional sorbents. While adsorption anionic arsenate V is in principle more feasible, there are only few adsorbents capable adsorbing both forms arsenic. this work, we explore potential two well‐known families Metal‐Organic...
The anti-biofouling and desalination properties of thin film composite reverse osmosis membranes (TFC-RO), modified by the incorporation copper iron nanoparticles, were compared. Nanoparticles metallic (CuNPs) an crystalline phase mix (Fe Fe2O3, FeNPs) obtained oxide-reduction-precipitation reduction reactions, respectively, characterized X-ray diffraction (XRD) transmission electron microscopy (TEM) techniques. Modified (PA+0.25Cu-PSL PA+0.25Fe-PSL) incorporating these nanoparticles during...
La regulación del trabajo en plataformas digitales es una de las asignaturas pendientes estados- nación sur global, donde factores diferente índole juegan contra para lograr mejorar condiciones quienes laboran dentro. El caso México se distingue por ser regiones socioeconómicas como Uber, tiene uno sus mayores mercados a nivel mundial. Sin embargo, iniciativas que han presentado ante el Congreso la Unión visto afectadas falta interés los conductores y consecuencia ausencia organización...
