“…The results indicated that citric acid and Na 2 CO 3 as an effervescence pair provided the highest extraction recovery for methadone. Regarding the effervescent time, bicarbonate has shorter effervescence time which may decrease the extraction recovery due to lower contact time between the extraction solvent and the ana-lyte [35]. Moreover, bicarbonate has lower thermal stability than carbonate [35].…”

“…Regarding the effervescent time, bicarbonate has shorter effervescence time which may decrease the extraction recovery due to lower contact time between the extraction solvent and the ana-lyte [35]. Moreover, bicarbonate has lower thermal stability than carbonate [35]. Therefore, the combination of citric acid and Na 2 CO 3 showed a longer effervescent reaction time compared to other sources because of the smooth release of the hydrogen ions and more persistent effervescent reaction.…”

A novel effervescent tablet‐assisted demulsified dispersive liquid–liquid microextraction based on the solidification of floating organic droplet was developed to determine methadone prior to gas chromatography with flame ionization detection and gas chromatography with mass spectrometry. In this method, a tablet composed of citric acid, sodium carbonate, and 1‐undecanol was utilized. The resulting effervescent tablet generated carbon dioxide in situ to disperse 1‐undecanol in the sample. Thus, the dispersive and extraction processes were performed in one synchronous step. An aliquot of acetonitrile as the demulsifier solvent was used for the separation of two phases instead of centrifugation. Under optimal conditions, the developed method was linear up to 50 000 µg/L with correlation coefficients higher than 0.99. Moreover, limits of detection and limits of the quantification were in the range of 3‐10 and 7‐30 µg/L in water and biological samples, respectively. Intra‐ and interday precisions (n = 6) of the spiked methadone at a concentration level of 50 µg/L were over ranges of 5.1‐6.8% and 5.7‐7.1%, respectively. The preconcentration factors and recovery values were obtained in the range of 140‐145 and 98.1 to 101.6% in real samples, respectively.

“…Yıldız and Çabuk proposed a tablet based on a tertiary mixture containing Na 2 CO 3, NaH 2 PO 4 and 1-dodecanol [ 44 ] for the extraction of fungicides from fruit juice. For the fabrication, all the ingredients were manually blended and cooled in a refrigerator to produce the solidification of the 1-dodecanol increasing the consistency of the tablet.…”

Dispersive microextraction techniques are key in the analytical sample treatment context as they combine a favored thermodynamics and kinetics isolation of the target analytes from the sample matrix. The dispersion of the extractant in the form of tiny particles or drops, depending on the technique, into the sample enlarges the contact surface area between phases, thus enhancing the mass transference. This dispersion can be achieved by applying external energy sources, the use of chemicals, or the combination of both strategies. Effervescence-assisted microextraction emerged in 2011 as a new alternative in this context. The technique uses in situ-generated carbon dioxide as the disperser, and it has been successfully applied in the solid-phase and liquid-phase microextraction fields. This minireview explains the main fundamentals of the technique, its potential and the main developments reported.

“…Dispersion techniques are commonly accelerated using manual shaking, magnetic stirring, air, vortex, surfactant emulsion, ultrasound, microwave, or effervescent tablets (Leong et al, 2014). An effervescent tablet is a soluble tablet that involves acid-base reaction that produces carbon dioxide (CO2) bubbles, thus making it possible for fine dispersion of extraction solvent in an aqueous sample (Yıldız & Çabuk 2018). This method is very rapid, effective, and reliable.…”

A rapid and straightforward method based on effervescent-assisted dispersive liquid-liquid microextraction combined with high-performance liquid chromatography-ultraviolet (HPLC-UV) detection for preconcentration of ketoprofen in water samples was developed. The extraction efficiency of ketoprofen drug was investigated using 23 central composite design. The values of optimum extraction condition were set as 300 µL volume of 1-dodecanol, three pieces of tablets, and 30°C extraction temperature. The runtime was conducted in less than 6 min using a non-polar C18 column and an isocratic mobile phase (acetonitrile: water of 40:60 (v/v)) at a controlled flow rate of 1 mL min-1. A good linear response was achieved in the range of 0.01–0.50 µg mL-1 (R2 > 0.990). Detection and quantification limits were calculated at 0.001 and 0.004 µg mL-1, respectively. The average recoveries at three spiking concentration levels were within the range of 85%–108% with RSD < 10% (n = 3). Real sample analysis was fortified using gel and standard solutions, and the calculated values were close to the actual values at 0.059 µg mL-1 (KET gel, initial concentration 0.075 µg mL-1) and 4.49 µg mL-1 (standard solution, initial concentration 5 µg mL-1), respectively.
