Solvent extraction in the primary and secondary processing of zinc
The traditional roast-leach-electrowin(RLE) zinc production route was developed for the processing of sulphide ores. It can prove inefficient for some complex sulphides and is not readily applicable to the treatment of other ore types. Inherent to this route is the generation of SO2 gas that has to be fixed for environmental reasons, usually resulting in the production of sulphuric acid. These ...
متن کاملIntegrated Pressurized Solvent Extraction-Cleanup for the Rapid Determination of Polychlorinated Biphenyls in Meat Samples
Um método rápido e eficiente, baseado na integração da extração com solvente sob pressão (PSE) com limpeza através do método sólido de extração (SPE) e sistema de cromatografia gasosa com detector por captura de elétrons (GC-ECD) foi desenvolvido para a determinação de bifenilos policlorados (PCBs). Seis indicadores e doze PCBs semelhantes à dioxina foram selecionados como analitos. Este método...
متن کاملSolvent replacement for green processing.
The implementation of the Montreal Protocol, the Clean Air Act, and the Pollution Prevention Act of 1990 has resulted in increased awareness of organic solvent use in chemical processing. The advances made in the search to find "green" replacements for traditional solvents are reviewed, with reference to solvent alternatives for cleaning, coatings, and chemical reaction and separation processes...
متن کاملSOLVENT EFFECTS AND CHEMICAL REACTIVITY Understanding Chemical Reactivity
This chapter reviews the theoretical background for continuum models of solvation, recent advances in their implementation, and illustrative examples of their use. Continuum models are the most efficient way to include condensed-phase effects into quantum mechanical calculations, and this is typically accomplished by the using self-consistent reaction field (SCRF) approach for the electrostatic...
متن کاملPlant Secondary Compounds; Their
Both the anti-nutritional and beneficial effects of secondary compounds in a range of temperate and tropical forages have been reviewed. Major secondary compounds in temperate and tropical forage plants occur in the phenolic fraction and include condensed and hydrolysable tannins, phenolic monomers and lignin. Condensed tannins (CT) bind to plant protein by pH-reversible hydrogen bonding. In te...
