In this work, a rapid method based on air-assisted liquid liquid microextraction (AALLME) was developed for the determination of three fungicides (azoxystrobin, diethofencarb and pyrimethanil) in water and juice samples. A narrow-neck glass tube was made to facilitate collection of the low-density extractant. The mixture of extractant and sample solution is rapidly sucked into a 5-mL glass syri...

In this paper we used a surfactant-stabilized lyotropic lamellar model system to study the interfacial behavior of an ion-extracting agent: N(1),N(3) dimethyl-N(1),N(3)-dibutyl-2-tetradecylmalonamide (DMDBTDMA). An analysis of small-angle X-ray scattering (SAXS) and polarized attenuated total reflectance-Fourier transform infrared (ATR-FTIR) data enabled us to describe the distribution of the m...

The extraction behavior of neodymium and other rare earths from nitric acid media by the functionalized ionic liquid trioctylmethylammonium dioctyl diglycolamate, [A336][DGA], was investigated. The nonfluorinated ionic liquid trioctylmethylammonium nitrate, [A336][NO3], was used as diluent. The extraction behavior of neodymium(III) in this ionic liquid solution was carried out as a function of ...

In order to efficiently remove phenolics from coal chemical wastewater, this study utilizes molecular simulation determine the most effective extractant. And extraction effect is verified through results. The energy of hydrogen bonding dominates extractant’s ability. interaction between phenols and solvent was examined using calculations, it discovered that strong H-bond CYC/1-PA synergistic ex...

a series of non-cyclic polyethers with different end groups and chain length were used for the extraction of lithium salt from aqueous into various organic phases viz. chloroform, carbon tetrachloride, 1,2-dichloroethane, to study the influence of structural variations within the extractant molecule upon the extraction selectivity and efficiency. the ionophores used were viz. deg (i), degdme (i...

Stereoisomers of monoamide highlight the importance extractant chirality for U/Pu extraction.

2,6-di(5,6-dipropyl-1,2,4-triazin-3-yl)pyridine (n-Pr-BTP), first developed in our laboratory, is a very promising extractant for the effective separation of actinides(III) from lanthanides(III). It is able to extract actinides(III) with usable distribution coefficient from 1-2 molar nitric acid selectively over lanthanides(III). The Am(III)/Eu(III) separation factor is approx. 135. The perform...

Investigation on the pectic substances of cashew (Anacardium occidentale L.) apple under different acid-extraction conditions (pH 1.0, 1.5, and 2.0) showed that more than 10%-25% of A. occidentale pectins (AOP) could be extracted, depending on the extractant strength. The extracted AOP contained high amounts of galacturonic acid (GalA: 69.9%-84.5%) with some neutral sugars of which rhamnose (Rh...

The extraction equilibrium of indium(III) from a nitric acid solution using di(2-ethylhexyl) phosphoric acid (D2EHPA) as an acidic extractant of organophosphorus compounds dissolved in kerosene was studied. By graphical and numerical analysis, the compositions of indium-D2EHPA complexes in organic phase and stoichiometry of the extraction reaction were examined. Nitric acid solutions with vario...

Human origin determination is an important aspect of blood grouping analysis in forensic science laboratories. In the present study, protein extractants like gel buffer, ammonia and saline employed for origin determination were evaluated and compared qualitatively and quantitatively for their role in the extraction of proteins from dried blood stained materials of human origin at regular time i...
