This paper presents the study of degradation pesticide atrazine, employing photoassisted electrochemical methods at a dimensionally stable anode nominal composition Ti/Ru0.3Ti0.7O2. All experiments were performed in flow cell, and effects current density, electrolyte rate, as well use different supporting electrolytes are reported. The results indicate that energy per order (EEO/kW h m-3 order-1) is substantially reduced when photochemical techniques combined. It observed complete atrazine...
While excess phosphorus typically results in the eutrophication of inland waters, there is growing evidence that nitrogen (N) and availability different N forms influence phytoplankton community composition, often favoring potentially toxic genera. In this study, environmental dynamics, structure, uptake rates were investigated two tropical reservoirs. Phytoplankton ammonium () nitrate acquisition was assessed through 15 addition experiments over 2 years. We found changes ambient nutrient...
Abstract Agricultural activities can affect the delivery of nutrients to streams, riparian canopy cover, and capacity aquatic systems process sediments. There are few measures nutrient uptake metabolism from tropical or subtropical streams in general, even fewer regions South America. We examined ammonium (NH 4 + ) soluble reactive phosphorus (SRP) retention Brazil Argentina. selected 12 with relatively little extensive agricultural activity conducted whole‐stream additions measurements...
Esta pesquisa teve como principal objetivo investigar os pro-cessos envolvidos nas transformações do nitrogênio em um sistema de lagoas estabilização. Em amostragem nictemeral (24 horas) observou-se forte estratificação térmica durante a maior parte ciclo amostrado qual condicionou compartimentalização vertical e química duas lagoas, possibilitando análise dos processos forma segmentada pela ACP (análise componentes principais), que mostrou-se ferramenta estatística muito útil na...
Integration of pulse amplitude modulated (PAM) fluorometry and conventional methods for estimating carbon assimilation in microalgae is important physiological, ecological economic purposes. In this study, we compared PAM carbon-14 (14C) uptake techniques to estimate the fixation rate Chlorella vulgaris under controlled laboratory conditions. The key parameter comparison was electron yield (Фe), commonly assumed when converting transport (ETR) values into chlorophyll-specific (PB)....
Esta pesquisa teve como objetivo principal comparar cinco métodos espectrofotométricos para determinação de proteínas em amostras provenientes estações tratamento efluentes sanitários. O intuito foi definir uma metodologia aplicação rápida, fácil e confiável este tipo amostra. As lagoas estabilização, sistemas biológico, têm principais constituintes proteínas, carboidratos lipídeos, mas também apresentam muitos compostos interferentes, por exemplo, uréia, detergentes fenólicos, que podem...
