Research on the extraction of Nickel(II) and Copper(II) using liquid membrane emulsion technique has been conducted. The purpose of this research is to know the influence of pH, extraction time and presence of competed metals (Ni2+ in Cu2+ and vice versa)... see more

90Sr (t1/2 = 28.8 a), one of the most significant fission products in high-level radioactive liquid waste (HLLW), contributes to a large part of the heat load and radiation. Removal of 90Sr from the HLLW is beneficial for the final treatment of nucle... see more

La synthèse sous irradiation micro-ondes (temps d’irradiation = 40 minutes, Puissance d’irradiation = 240 Watts), la caractérisation et l’application de nouveaux agents extractants organophosphorés de type acides alkylaminobiméthylène diphosphon... see more

Cette étude concerne l’extraction de La(III) par la technique d’extraction liquide-liquide en utilisant un liquide ionique modifié (LI) de l’Aliquat 336. La caractérisation du liquide ionique est faite par spectroscopie IRTF, test au AgNO3, chromatographi... see more

This paper describes a method for the simultaneous detection and quantification of six sul-fonamides in chicken meat using normal phase cartridge clean-up and HPLC with UV detection . A liquid – liquid extraction and Sep- Pak silica clean-up procedure ... see more

ABSTRACTAedes aegypti is the main vector of dengue virus carriers. One alternative to deal with these problem is by using insecticides derived from the leaves of breadfruit (Artocarous altilis) with the method of liquid electric. The research was purely e... see more

BACKGROUND: A new simple, selective and accurate high-performance liquid chromatographic (HPLC) method utilising solid-phase extraction for the determination of pantoprazole in human plasma samples has been developed. AIM: The purpose of this paper was de... see more
