Nitrite (NO2−) is toxic to fish. High levels of NO2− may develop in natural aquatic environments or in aquaculture systems, a situation that is aggravated in tropical regions by high temperatures and low dissolved oxygen. The toxicity of NO2− was evaluated in the Amazonian fish, Colossoma macropomum to define the environmental quality standards and management of culture system for this species. The acute toxicity of NO2− was tested using a renewal bioassay system and a series of increasing NO2− concentrations ...

The esterification of free fatty acids (FFA) is an alternative for the production of biodiesel from oils with high concentrations of FFA. In this paper, catalysts for the esterification of oleic acid with methanol were prepared from two Amazon kaolins (Century and flint) and two standard kaolins (KGa-1b and KGa-2) that were thermally treated at 950 °C and leached with 4 M sulfuric acid solutions. The activated metakaolin samples were characterized by X-ray diffraction, scanning electron microscopy, ...

Amazon flint kaolin, considered useless from an economic and industrial point of view, was calcined at 850 and 950 °C to obtain metakaolin samples. These samples were subsequently treated with sulfuric acid (4 M) by assisted heating with microwave radiation. The prepared samples were characterized by X-ray diffraction, scanning electron microscopy and N2 physisorption; the surface acidity was determined by titration with 0.2 M KOH. The materials obtained were used as catalysts in the esterification ...

The buriti palm (Mauritia flexuosa) is a palm tree widely distributed throughout tropical South America. The oil extracted from the fruits of this palm tree is rich in natural antioxidants. The by-products obtained from the buriti palm have social and economic importance as well, hence the interest in adding value to the residue left from refining this oil to obtain biofuel. The process of methyl esters production from the buriti oil soapstock was optimized considering acidulation and esterification. ...

Boron doped diamond films (BDD) are the most studied electrocatalytic materials and their efficiency for removing organic compounds is attributed to their ability to produce a large amount of hydroxyl radicals by the electrolysis of water.However, some organic compounds are easy to degrade than others, as well as they also interact with BDD surface.Thus, it is necessary to understand the chemical/electrochemical process at the molecular level.In this frame, this work aims to study the electrochemical ...

The synthesis of aluminosilicate Al-MCM-41 was performed using mining kaolin waste as an alternative source of silicon and aluminum to add value to this waste. In a preliminary stage, acid leaching was carried out with the kaolin residue with three different durations (1, 1.5 and 2 h) to evaluate the leaching time that provided the highest amounts of silicon and aluminum in the tailings. Molecular sieves were synthesized by the hydrothermal method and calcined at 550 °C to eliminate the surfactant. ...

Anemia and iron deficiency anemia have been known to cause significant functional impairment, lower quality of life, and higher morbidity and mortality and may be correlated with an impact on the cost of treatment. OBJECTIVE: The aim of this study was to estimate the prevalence and risk factors for anemia and iron deficiency anemia in patients with IBD in a tertiary IBD ...
