Porém, devido aos riscos à saúde dos laboratoristas, uma alternativa é o uso do ácido ascórbico (AA). Entretanto, modificações no protocolo de análise podem induzir a variações nos resultados, havendo a necessidade de padronizá-las e calibrá-las.

Abstract:

It is known that RC industrial structures are liable to the effects of crude oil products, which may have a disadvantageous influence on their exploitation and safety. Within this research, the influence of crude oil products on the physico-mechanical properties of mature concrete, as well as other possible mechanisms of RC progressive failure have been analysed. Crude oil products with a very low neutralisation number were found to be physico-chemical active agents affecting concrete.

Kraj ten dopiero na początku XX wieku wkroczył na drogę uprzemysłowienia, reinwestując część środków uzyskanych z eksportu ropy naftowej. Sektor naftowy stopniowo stał się głównym źródłem dochodów, które można było przeznaczyć na rozwój kraju oraz innych niż naftowa dziedzin gospodarki. Z drugiej strony nadmierna dominacja sektora naftowego okazała się szkodliwa dla rozwoju innych sektorów, a szczególnie przemysłu przetwórczego. Przemysł samochodowy, odnoszący początkow

Abstract:

Many modern technologies for treatment of soil polluted with oil products are developed through creation of new and efficient bio-agents that help to degrade oil products. Another trend in development of new technologies aims to speed up the growth of soil microorganisms, this way accelerating biodegradation of oil products without the help of introduced microorganisms. The biodegradation of diesel fuel and heavy fuel oil was tested in the soil using chemical additives (oxidizing agents). The tests aimed to ascertain the impact of H2O2, KMnO4 and MnSO4 on residual concentrations of heavy fuel

Effective clean-up of oil spills due to their negative environmental and economic impact is of capital importance. Clean-up of oil by sorption is considered one of the most desirable choices, because oil can be completely removed without causing any secondary pollution. Natural organic sorbents had been investigated and developed to control oil products‘ spills. Plant biomass is a renewable resource which can be converted into various materials and energy. Hemp (USO-31), as a textile industry waste, was used as an oil product sorbent material. The present study examines hemp sorption capacity
