Municipal Solid Waste Incineration (MSWI) fly ash contains significant amounts of leachable metals, and is therefore considered as hazardous waste. The increased amounts of fly ash generated cause environmental issues, management costs and accumulation of valuable metals in landfills. All these factors contribute to an increased interest in recognizing the ash as an urban mining target of metal...

Lithium extraction from salt lake brine with a high mass ratio of Mg/Li by counter-current method using TBP-DIBK system was investigated in this study. In the process, TBP and DIBK acted as extractant, kerosene used diluent, FeCl3 co-extractant. The operation conditions extraction, scrubbing, stripping, regeneration were investigated. study, 5.5 mol/L LiCl + 0.5 HCl scrubbing solution for purif...

An efficient recovery of lithium (Li(I)) from salt lakes is currently a challenging issue. Herein, we report feasible extraction Li(I) simulated lake solution using novel system, in which functionalized ionic liquid (FIL) dissolved different diluent. As functional extractant, 3-methyl-1-octylimidazolium thenoyltrifluoroacetone [Omim][TTA] was successfully prepared simple way and its performance...

Solvent extraction studies of copper and zinc have been carried out using Versatic 10 acid and Cyanex 272 separately from a model brass pickle liquor. Various parameters for the extraction and separation of copper and zinc such as effect of pH, extractant concentration, phase ratio etc. have been optimized. It was observed that copper was almost completely extracted into the organic phase compr...

Hydroxyanthraquinones represent a group of pharmacologically active compounds characteristic for plants of the Rumex and Rheum genera. These compounds in the human intestine act as laxative compounds. As they cause the greatest side effects and are often abused by the public, their accurate analysis in plants and plant-derived laxatives is much needed. To isolate compounds from plants, pressuri...

Coal is most important fossil fuel in world. Energy requirement of world is increasing in many fields day by day. The crude oil and coal are the main backbone of energy. Since the reserves of crude oil are decreasing day by day as a result the coal becomes the main sources of fossil fuel. Ash content of Indian coal is very high ranging from 15% to 55% [1]. Ash is an inorganic compound present i...

This paper reports the selective separation of zinc over iron from spent pickling wastes or effluents using two different membrane-based solvent extraction process configurations, Nondispersive solvent extraction (NDSX) and emulsion pertraction technology (EPT). The process aims to obtain a highly concentrated zinc solution with a negligible content of iron to allow for Zn electrowinning. The e...

osting by E Abstract A simple spectrophotometric method was developed for the simultaneous determination of five commercial cationic dyes at 2.0 8.5 lg L 1 level after using diatomite as solid-phase extractant. The method is based on preconcentration of the five dyes on natural diatomite solid-phase extractant and on multivariate calibration using partial least squares method (PLS-1). Compared ...

This is a communication on the removal of copper(II) ions from a residual mine water using an emulsified liquid membrane (ELM). The membrane was prepared by dissolving the extractant LIX-860 (a salicylaldoxime), used as a mobile carrier, and Span80, a surfactant, in kerosene. The ELM allowed an efficient metal transport from the feed solution towards the strip liquor, in experiments carried out...
