We discuss the origins and the fundamentals of Green Analytical Chemistry (GAC), based
on the literature published about clean, environmentally-friendly or GAC methods. We pay …

Solid-phase microextraction (SPME) is a simple, sensitive, rapid and solvent-free technique
for the extraction of analytes from gaseous, liquid and solid samples and takes a leading …

Introduced in 1999 as a novel solventless sample preparation method, stir-bar sorptive
extraction (SBSE) has become a popular analytical technique for the pre-concentration of …

The Fe nanoparticles were synthesized using eucalyptus leaf extracts. The low cost and
locally available laterite was used as a source of iron rather than using iron salts (Ferrous …

Polycyclic aromatic hydrocarbons (PAHs) are compounds widespread in the environment,
many of them showing carcinogenic effects. These compounds can reach the food chain by …

Stir bar sorptive extraction (SBSE) was introduced in 1999 as a solventless sample

The determination of trace residues and contaminants in complex matrices, such as food,
often requires extensive sample extraction and preparation prior to instrumental analysis …

The most recent contributions on solventless extraction techniques have been reviewed.
This paper deals with those techniques that use solid phases, such as solid-phase …

Molecular imprinted solid-phase extraction is the technique that uses molecular imprinted
polymer as the sorbent in solid phase extraction. Molecular imprinted solid-phase extraction …

Modern trends in analytical chemistry are towards the simplification and miniaturization of
sample preparation, as well as the minimization of organic solvent used. In view of this …
