extraction of trace amounts of toxic heavy metals from complicated environmental matrixes is a  challenging task. the aim of this investigation is the comparison of the extraction efficiencies and other related experimental variables ( chemicals, effect of ph, potential interfering ions) on the determination of inorganic lead ( ) which is present in waste water of dye industries. compared techn...

A higher yield of glycoalkaloids was recovered from potato peels using pressurized liquid extraction (1.92 mg/g dried potato peels) compared to conventional solid-liquid extraction (0.981 mg/g dried potato peels). Response surface methodology deduced the optimal temperature and extracting solvent (methanol) for the pressurized liquid extraction (PLE) of glycoalkaloids as 80 °C in 89% methanol. ...

The use of liquid-liquid extraction for the separation of tantalum from niobium was demonstrated. Tantalum and niobium spectrographically free of each other were prepared in quantity on a continuous basis.

With a microfluidic droplet-based liquid/liquid extraction setup, we demonstrate that the extraction of an ionic analyte from complex matrices can be modulated by the interfacial Galvani potential difference and the extraction equilibrium follows the classical Nernst equation.

In this work, the GEneralised Multifluid Modelling Approach (GEMMA) is applied to simulation of liquid–liquid extraction in a Rotating Disc Column (RDC) and Pulsed Sieve-plate Extraction (PSEC). A mass transfer modelling methodology developed, which multiphase flows, droplet size distribution dispersed phase holdup predicted with computational fluid dynamics are coupled correlations predict ove...

This paper demonstrated a fluorescence-indicated mass transfer liquid-liquid extraction process based on a droplet microfluidic system. Analysis of the droplet-based liquid-liquid extraction process based on the description of mass transfer into or out of droplets is conducted. The relationship between the extraction efficiency and the droplet size is measured and the mass transfer coefficient ...
