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 …

Dispersive liquid–liquid microextraction (DLLME) is a modern sample pretreatment
technique that is regarded as consilient with the current trends of modern analytical …

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

This manuscript covers the application of the main techniques for simultaneous optimization
of multiple responses generated by the application of multivariate designs (two-factor …

In this work, central composite design (CCD) combined with response surface methodology
(RSM) and desirability function approach (DFA) gives useful information about operational …

Copper oxide nanoparticles loaded on activated carbon (CuO-NPs-AC) were prepared and
fully analyzed and characterized with FE-SEM, XRD and FT-IR. Subsequently, this novel …

Dispersive liquid-liquid microextraction (DLLME) techniques have attracted considerable
interest because they are cost effective, easy to operate, and reliably preconcentrate trace …

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 …

The recent developments in hollow fiber liquid phase microextraction and dispersive liquid–
liquid microextraction are reviewed. Applications of these newly emerging developments in …

Maximum malachite green (MG) adsorption onto ZnO Nanorod-loaded activated carbon
