Chemometric approaches have been increasingly viewed as precious complements to high
performance liquid chromatographic practices, since a large number of variables can be …

Nowadays, the trend to simplify and miniaturize sample preparation methods has resulted in
the development of effective and low-cost microextraction techniques that utilize a very small …

During the past 7 years and since the introduction of dispersive liquid–liquid microextraction
(DLLME), the method has gained widespread acceptance as a simple, fast, and miniaturized …

The simultaneous and competitive ultrasound-assisted removal of Auramine-O (AO),
Erythrosine (Er) and Methylene Blue (MB) from aqueous solutions were rapidly performed …

Activated carbon was prepared from walnut wood which was locally available, non-toxic,
abundant and cheap. This new adsorbent was characterized using BET, FTIR and SEM …

This paper presents an extraction method based on dispersive-nanoparticle-solid phase
microextraction (DNSPME) for the preliminary preconcentration and subsequent …

In this study, we assessed the simultaneous removal of Cu (II) and Zn (II) from aqueous
solutions, using Chitosan/Hydroxyapatite/nano-Magnetite (Fe 3 O 4) composite as an …

The aim of this study was to synthesize Ca (II)-doped chitosan/β-cyclodextin and to
investigate its potential as a sorbent for removal of acetaminophen from aqueous solution …

Novel solvent microextraction techniques are presently receiving a great deal of interest
from analytical chemists, as confirmed by the constantly increasing number of published …

Abstract The Chitosan/Hydroxyapatite/Snail-Shell/nano-Magnetite composite was used in
this experiment to remove Zinc (II) and Cu (II) ions from the aqueous medium concurrently. A …
