Among the “traditional” hydride-forming elements, lead is probably the most difficult, and its determination in this form has rarely been reported in the literature. In this paper a simple and rapid method, axial-view ...

An interference-free, fast, and simple method is proposed for Pb determination in environmental solid samples combining slurry sampling and electrothermal atomic absorption spectrometry. Samples were ground to an adequate ...

The wet oxidation of organic compounds with CO2 and H2O has been demonstrated to be an efficient technique for effluent treatment. This work focuses on the synthesis, characterization and catalytic performance of Fe-MnO2/CeO2, ...

The sludge generated during the water treatment process to supply the population is discarded in most of the time, without adequate treatment in the water bodies, causing negative environmental impacts to the environment. ...

The  synthesis  of  carboxymethylcellulose  was  investigated  using  effluents  containing  short  cellulose  fibers.  Carboxymethylcellulose  was  synthesized  according  to  the  slurry  process  using  different  amount  ...

With the development and expansion of the oil industry, waste generation on a large scale also grows. Environmental contamination by oil and its products stands out as a problem of high impact and requires special care ...
