Cover Story: Effervescence-assisted microextraction is a method that is based on the use of weak acids and carbonate salts to generate CO2 bubbles in water to disperse a sorbent medium into an aqueous solution and facilitate the extraction of analytes. Although the main role of effervescence is the dispersion and mixing of the sorbent, several experimental factors are also affected, which play a pivotal role in the extraction efficiency. These include the pH of the solution, the ionic strength and the extraction time. This work assesses for the first time the influence of effervescence on these parameters and tries to elucidate general guidelines on how to select the effervescence reagents that provide a comprise between the efficient dispersion of the sorbent medium and the experimental conditions that maximize the extraction efficiency.
