Arsenic contamination requires accurate quantification. Microextraction techniques (METs) offer an eco-friendly solution, improving analytical procedures by reducing solvent use and enhancing efficiency for environmental monitoring.
Area of Science:
- Environmental Science
- Analytical Chemistry
Background:
- Arsenic poses significant environmental and ecological risks due to its toxicity.
- Accurate quantification of arsenic is essential for risk assessment and mitigation.
- Traditional sample preparation methods face challenges with complex matrices and trace-level analysis.
Purpose of the Study:
- To highlight the importance of microextraction techniques (METs) in arsenic analysis.
- To present METs as a green and efficient alternative to conventional sample preparation.
- To discuss advancements in solid phase microextraction (SPME) and liquid phase microextraction (LPME).
Main Methods:
- Review of microextraction techniques (METs) as advanced sample preparation methods.
- Focus on solvent-free (SPME) and reduced-solvent (LPME) approaches.
- Discussion of developments in sorbent materials and online applications for SPME, and new solvents for LPME.
Main Results:
- METs offer improved extraction efficiency, speed, and automation.
- These techniques significantly reduce solvent consumption, aligning with green chemistry principles.
