Black carbon (BC), the product of incomplete combustion fossil fuels and biomass (called elemental (EC) in atmospheric sciences), was quantified 12 different materials by 17 laboratories from disciplines, using seven methods. The were divided into three classes: (1) potentially interfering materials, (2) laboratory‐produced BC‐rich (3) BC‐containing environmental matrices (from soil, water, sediment, atmosphere). This is first comprehensive intercomparison this type (multimethod, multilab,...
Due to steady increase in use and mass production carbon nanotubes (CNTs) will inevitably end up the environment. Because of their chemical nature CNTs are expected be recalcitrant biotransform only at very slow rates. Degradation within days has recently been reported, but excluding one study, conclusions relied solely on qualitative results. We incubated 13 different types subjected them enzymatic oxidation with horseradish peroxidase concluded that analytical methods commonly employed for...
Black carbon (BC), the soot and char formed during incomplete combustion of fossil biomass fuels, is ubiquitous, participates in diverse environmental processes, has adverse effects on human health. However, uncertainty persists regarding how accurately present measurement methods quantify total BC or even defined subportions continuum. Hence, we sought to improve this situation by developing a new, low-sample manipulation methodology that does not require any oxidative pyrolytic treatments...
Water pollution and scarcity are two of the most serious problems humanity is currently facing. Therefore, it important to develop effective inexpensive technologies treatments remove key pollutants from water. Zr based Metal-Organic Frameworks (MOFs) new materials with potential organic inorganic pollutants. However, critically analyze their performance in laboratory trials evaluate scalability for wastewater treatment. This document presents a critical review recent studies advances...
Advanced oxidation processes based on photocatalytic generation of • OH radicals have emerged as promising technologies for the removal recalcitrant pollutants in water. However, their poor recyclability has reduced potential large-scale application. Herein, a Fe 3 O 4 -embedded ZnO system been prepared and its activity was evaluated by monitoring photo-assisted bleaching p-nitrosodimethylaniline ( pNDA). Water disinfection performance determined measuring Escherichia coli inactivation under...
Abstract In this work, the magnetic and photocatalytic ZnFe 2 O 4 /ZnO, at two different ratios (1 : 1 8), have been prepared via a simple one‐step method. Characterization of nanocomposite was performed using Dynamic Light Scattering (DLS), Fourier Transformed Infrared Spectroscopy (FTIR), X‐Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Brunauer‐Emmett‐Teller (BET) isotherm. The activity evaluated by monitoring photodegradation methylene blue photo‐assisted bleaching p...
Los microplásticos (MPs) ya se consideran como contaminantes emergentes debido a que encuentran en todos los cuerpos de agua han analizado y pueden tener efectos adversos la salud humana. Estimar cantidad el tipo MPs aguas superficiales es relevante para poder entender problemática. Sin embargo, aún no tiene una metodología establecida determinación cuantitativa cualitativa estos medios acuáticos por esta falta estandarización comparación entre artículos vuelve complicada. Una estándar...
Access to clean water remains a global challenge, particularly in areas where populations rely on surface which may contain pathogen microorganisms or other contaminants. To meet drinking standards these sources must be treated. Coagulation with chemicals causes environmental problems and adverse effects human health they are normally difficult obtain. Natural coagulants obtained from papaya (Carica papaya) waste presented here as an alternative option that is safe for health, non-polluting...
The increase in human activities generates additional and more frequent problems related to the availability of water for consumption.Sodium benzoate is a compound mainly used as preservative food industry, but it has found other applications fields such anticorrosive medicine off-label therapeutic agent.Studies have shown that anthropogenic releases sodium environment adverse effects on different organisms.This paper presents study process photochemical transformation by exposure UV...
