The main factors responsible for the oxidative processes of biodiesel are oxygen, metal traces, high temperature and amount unsaturated fatty acids. quality is harmed by oxidation products, which corrosive to engine chambers may lead clogging injection pumps filters, besides increasing viscosity. Thus, this work aimed at investigating stability corn biodiesel, obtained base-catalyzed transesterification reaction, using ethanol route. As-synthesized, stored heated samples were characterized...
Considering the nutraceutical properties, high commercial value from pigments and essential lipids environmental sustainability, purposes of this study were to assess major carotenoids fatty acids composition nine microalgae species as a source compounds raw material for biodiesel production. The carotenoid acid content analyzed by performance liquid chromatography tandem mass spectrometry detection method with atmospheric pressure chemical ionization mode (HPLC/APCI-MS/MS) resolution gas...
PRODUCTION. In this work, the fatty acid quantity and composition of six freshwater microalgae soybean grains was determined by direct transesterification gas chromatography analysis.The results showed that all species presented a higher than grain.Choricystis sp.(A) provides 115% more acids per gram biomass grain.With regard to composition, Choricystis an adequate proportion saturated unsaturated acids, with lower polyunsaturated and, akin some marine microalgae, constitutes alternative raw...
ABSTRACT Mining activities generate large amounts of waste in the form mud that is disposed containment dams. When such dams collapse, serious accidents can happen, like one occurred Brumadinho, Minas Gerais, Brazil, killing 272 people and contaminating rivers areas native forests. On other hand, there are also two types plastic which after production use environment or landfills, causing contamination leading to release microplastics: (1) scraps from textile industry (2) polyethylene...
Early diagnosis is crucial for successful cancer treatment. As a mitochondrial metabolic disease, produces volatile organic metabolites that are present in earwax, allowing differentiation between healthy individuals and those with through an assay called cerumenogram. In this case series study, we demonstrated also enables the of precancerous stages, such as hypermetabolic inflammation dysplasia, which can aid treatments to prevent progression. Additionally, reveals oncological metabolism...
Parâmetros que influenciam a eficiência da degradação do glifosato (adição única de Fe 2+ , adição simultânea e 3+ numa razão molar 1:1 (Fe /Fe ), íons oxalato H 2 O ) foram avaliados em escala laboratório.Efeitos sinérgicos sobre formação fosfato observados utilizando bem como adicionando oxalato.Por outro lado, aumentos nas concentrações não proporcionaram incremento linear mineralização liberação fosfato.Utilizando elevadas dessas espécies, foi constante ou até mesmo reduzida.Sob...
The existing techniques for the removal of heavy metals are expensive and frequently inefficient. Thus application biosorbents has arisen as an alternative, this being emergent technology that must be studied explored, with aim promoting better environmental human life quality. objective study was to verify capacity active inactive Pleurotus ostreatus fungal biomass in removing Cr(VI) ions by biosorption from synthetic aqueous solutions these at concentrations 10, 25, 50, 75, 100, 125 150 mg...
