Extrakcie spľňajúce princípy zelenej chémie využívané v stopovej analýze kovov

Abstrakt

An increasing interest in rapid, cost-effective, and environment-friendly sample preparation techniques leads to the development of extractions which are compatible with the principles of green chemistry. This review provides basic principles and current applications of the extractions useful in (ultra)trace analysis of metals. These techniques include: supercritical fluid extraction, pressurized hot-water extraction, ultrasound-assisted extraction, liquid-liquid microextraction, dispersive liquid-liquid microextraction, cloud point extraction, solid-phase microextraction, and microwave-assisted extraction.
