The development of new technologies for water and wastewater treatment is a growing need due to the occurrence micropollutants, such as dyes, in resources. In this sense, green-synthesized nanoparticles are being extensively studied, their low cost, non-toxicity, high efficiency adsorption processes. Thus, present study reports green synthesis copper oxide (CuO-NP), obtained from pomegranate (Punica granatum) leaf extract, employed removal Safranin-O (SO) dye. CuO-NP was characterized by...
Drugs are being registered in water resources around the world, becoming a palpable environmental problem by altering natural characteristics of and, consequently, environment living organisms. Many techniques can be used to remove drugs present contaminated waters, among them stands out adsorption process. In this work, metformin, an antidiabetic drug, using commercial zeolite as adsorbent was investigated. The material characterized Fourier Transform Infrared Spectroscopy (FTIR), Scanning...
The combination of coagulation/flocculation and ultrafiltration in the process drinking water treatment was investigated using natural (chitosan) chemical (aluminum sulfate) coagulants. A 0.1 μm single-channel membrane applied at pressures 1 bar 2 bar, principle crossflow filtration. final produced quality assessed considering efficiency removal color, turbidity, COD, compounds that absorb UV 254 nm, among other physico-chemical microbiological parameters. with chitosan as coagulant (CFQ)...
In this article was developed a green synthesis of CuO nanoparticles on vegetal activated carbon (VAC), using pomegranate leaf extract as reducing and stabilizing agent in the removal multiple pollutants. The impregnated carbons with were characterized morphologically structurally. SEM XRD analysis, after modification, showed that surface structure remained porous sizes between 40 78 nm. As concern to contaminants atrazine, caffeine diclofenac, it is observed maximum adsorption capacities...
Considering the need for new technologies removal of pesticides from aqueous environment, Moringa oleifera seed husks (h-MO) were investigated diuron adsorption contaminated water at different temperatures and solute concentrations. The biosorbent used in this study was characterized by chemical, structural textural analyses. best experimental condition biosorption determined evaluating mass pH solution. We found a good capacity herbicide where maximum 14.74 mg/g 5 45°C. In addition, process...
A novel modification technique employing a layer-by-layer (LbL) self-assembly method, integrated with pressure-assisted filtration system, was developed for enhancing commercial polyethersulfone (PES) microfiltration (MF) membrane. This involved the incorporation of tannic acid (TA) in conjunction graphene oxide (GO) nanosheets. The effectiveness LbL method confirmed through comprehensive characterization analyses, including ATR-FTIR, SEM, water contact angle (WCA), and mean pore size...
Lead is a heavy metal considered highly toxic, responsible for causing several health problems as well being extremely harmful to fauna and flora. Given this fact, techniques have been studied the removal of from contaminated water, in which stands out adsorption. In sense, objective study was evaluate potential lead(II) biosorption water by seed husks, seeds pods Moringa oleifera Lam (moringa). Biomass characterized energy-dispersive X-ray spectroscopy, Scanning Electron Microscopy Fourier...
The aim of this study was the development a new magnetic coagulant based on nano structured iron oxide functionalized by Moringa oleifera (MO) compounds present in aqueous saline extract, for water treatment, with removal physical-chemical indicatives parameters, turbidity, apparent color, and absorption at UV 254nm (UV ).The oxide(maghemite, γ-Fe 2 O 3 ) synthesized without organic solvents use.These nanoparticles were MO (without oil, extracted ethanol hexane) extract.Tests coagulation...
Atrazine is an herbicide which widely applied in sugarcane and corn crops. Its frequent use has resulted environmental impacts, its traces have been verified surface groundwater. Thus, it necessary to remove this pollutant, alternative the adsorption due universal nature, low-cost ease of operation. Therefore, objective present work was study capacity atrazine by modified Moringa oleifera Lam. seed husks, a adsorbent. The biosorbent subjected c hemical thermal treatment characterised...
Abstract The present work aims at impregnating copper oxide nanoparticles (Cu NPs) on activated carbon by means of green synthesis with Moringa oleifera leaf extract to develop a material remove contaminants from water. produced materials were characterized their textural (specific surface area), morphological (Transmission Electron Microscopy), and structural (X‐ray Diffraction) properties. Particles size was estimated Scherrer equation the elemental concentrations Total Reflection X‐ray...
