The continuous increase in the use and release of pesticides is worrisome because water contamination can affect health environment. This study optimized validated a multi-residue method water. was developed using QuEChERS (Quick, Easy, Cheap, Effective, Rugged, Safe) followed by ultrahigh- performance liquid chromatography coupled to tandem mass spectrometry (UHPLC-MS/MS). validation performed on matrix (river water) regarding accuracy, precision, linearity, limits detection (LODs)...
The correct disposal and reuse of solid waste has been the subject several studies in recent years.A residue composed activated carbon diatomaceous earth generated by candies industry purification syrups was characterized recovered washing heat treatment.The process optimized using an experimental design, varying concentration solvent, time temperature.The planning indicated a strong influence initial dosis solvent (ethanol 95 %) recovery surface area residue.After washing, treatment at 800...
The development of new methods for the removal taste and odor compounds (MIB GEOSMINE) in supply waters with seasonal problems have been constantly tested.A completely accepted technology that can be efficient used at any drinking water treatment facility is not yet available.The search different associated techniques has demonstrated an increase these, being most adsorption method.The peach stone, agroindustrial residue, proved to relevant potential use as activated carbon precursor...
O carvão ativado pulverizado quando bem embalado e estocado não possui um prazo de validade regulamentado. Em geral, esta é determinada acordo com requisitos estabelecidos pelo próprio fabricante está diretamente relacionada a uma estimativa tempo superior ao em que o produto ficará no cliente até sua utilização. Neste trabalho, avaliou-se eficiência carvões ativados base seca umectados, relacionando parâmetros capacidade adsortiva (índice iodo umidade) destes materiais tempo. Os contendo...
Activated carbon is commonly used as a material for contaminant-adsorption processes in aqueous systems. However, its use more restricted to charcoal than coal, the most part, view of fact higher cost (~ 40%) if mineral fossil fuel which needs be extracted from earth by mining. For this reason, peach stone that comes alimentary industrial tailings can good choice separation pollutants suspensions and other soluble substances. The purpose research was development low-cost filter, using stones...
The efficiency of removal HMF in glucose syrup by using activated carbon was analyzed this work.Adsorption studies were carried out different adsorbent materials (activated pinus charcoal, mixture charcoal pinus/terra diatomaceous (70:30) and bituminous mineral coal), analyzing the behavior each one, as well its physical chemical properties.The results have showed that all carbons efficient for with efficiencies above 90 % despite dosages required carbon.
The presence of drugs in aquatic environments is an emerging problem, since the removal conventional water and sewage treatment systems has not shown to be efficient.The application alternative adsorbent materials may a resource exploited economically viable processes.Materials that are normally discarded nature, such as industrial waste, can reused systems, improving their efficiency adding value waste.Examples these boiler shell residues, Resíduo de casca caldeira (RCC) Portuguese, which...
A busca por solucoes para a minimizacao dos residuos nas industrias tem sido maior cada ano, seja otimizacao de seus processos e reducao custos industriais ou pelas exigencias orgaos ambientais pelo enquadramento em sistemas sustentaveis. O residuo solido gerado pela moinha carvoes vegetais, comumente descartados aterros industriais, foi caracterizado apresentou estabilidade termica, porosidade uma area superficial capaz adsorver ions metalicos meio aquoso com eficiencia. BET 330 m 2 /g, que...
The search for solutions to waste minimization by the industry has increased every year, either optimizing their processes and reducing manufacturing costs or meeting requirements of environmental agencies in sustainable systems framework.The solid generated milling vegetable charcoal, commonly discarded landfills, been characterized showed thermal stability, porosity surface area capable adsorbing metal ions an aqueous medium efficiently.The residue had a BET 330 m 2 /g, which corresponds...
