Single-drop microextraction (SDME) has been recognized as one of the simple miniaturized
sample preparation tools for the isolation and preconcentration of several analytes from a …

After its introduction just over twenty years ago, single-drop microextraction (SDME) became
a widely applied solvent-based microextraction procedure as a practical sample preparation …

Polycyclic aromatic hydrocarbons (PAHs), as an important class of pollutants, are persistent
in the environment and have adverse effects on human health, including carcinogenicity and …

In this work, the sensitive detection of hydrogen sulfide (H2S) was realized at low cost and
high efficiency through the application of silver–gold core–shell nanoprism (Ag@ Au-np) …

Single-drop microextraction (SDME) techniques are efficient approaches to pretreatment of
aqueous samples. The main advantage of SDME lies in the miniaturization of the solvent …

A novel density-tunable liquid-phase microextraction (DT-LPME) system was developed
with high-density deep eutectic solvents (DESs) as extractant and low-density organic …

Cellulose acetate fibers were modified with a gelatin cryogel adsorbent incorporating an iron–
carboxylate metal–organic framework and hypercrosslinked polymer composite. The hybrid …

Polycyclic aromatic hydrocarbons (PAHs) are one species of persistent organic pollutants
(POPs) with strong carcinogenicity and teratogenicity. They can be widely found in the …

Miniaturized extraction techniques are well established in analytical protocols following the
guidelines of green chemistry. In spite of this, analytical chemistry researchers continue to …
