Applications provides detailed information on membrane separation technologies as they …

In recent years, liquid-phase microextraction (LPME), a microscale implementation of liquid–
liquid extraction, has become a very popular sample pretreatment technique because it …

This article reports the extraction of Hg (II), Cd (II) and Cr (III) ions from acidic media using
new supported liquid membranes (SLM). The novelty of this work is the use of an ionic liquid …

A method has been developed for carrier-mediated hollow-fiber liquid-phase
microextraction (HF-LPME) and enrichment of multiple classes of antibiotics in water …

A rapid, efficient, and new solvent terminated dispersive liquid–liquid microextraction
technique coupled with HPLC was developed for selective extraction and analysis of s …

An optimised extraction and cleanup method for the analysis of pesticide in natural water
samples is presented. Sixteen pesticides of different polarity and from the different chemical …

In this paper the most recent developments in the microextraction of polar analytes from
aqueous environmental samples are critically reviewed. The particularities of different …

Two supported liquid membranes (SLMs) containing two different carriers but formed by the
same polymer support polyvinylidene difluoride (PVDF) and the same organic phase …

Even a cursory perusal of any analytical journal will demonstrate the increasing important of
trace and ultra-trace analysis. And as instrumentation continues to develop, the definition of …
