Green Extraction Techniques

2023
Green extraction of natural products was and will always remain an important research subject in various fields. It is based on developing techniques that meet the six principles of eco-extraction. This concept responds to the challenges of the 21st century, aiming to protect the environment, the operator, and the consumer by reducing hazardous solvent

Extraction Techniques in Green Analytical Chemistry

2023
Analytical chemistry determinations are not exempted from generating environmental contamination. A variety of strategies are now being proposed to reduce the impact on the environment caused by the different stages of the analytical process. These strategies can focus on the different stages of the analysis, ranging from sample collection and ...

Green's second theorem and the extraction of Green's functions

SEG Technical Program Expanded Abstracts 2009, 2009
We derive four distinct identities for Green's functions, based on the generalized second theorem of Green. One of them is the generalized first theorem of Green, which can be used to derive the source-receiver reciprocity relation for Green's functions.

Green-Membrane Extraction

2017
Analysis of real samples is usually associated with the need for proper sample treatment, which is traditionally performed by liquid-liquid extraction or solid phase extraction. During recent years, membrane extractions were proposed as an alternative for pretreatment of various real samples.

Modern Green Extraction Techniques

2023
Over the years, the topic of microextractive methods capable of generating high recovery values of analytes even from very complex matrices has received increasing attention. Techniques such as dispersive liquid-liquid microextraction (DLLME), microextraction by packed sorbent (MEPS), liquid-liquid extraction (LLE), solid phase microextraction (SPME ...
