Preconcentration/Extraction of Phthalate Esters in Milk Samples Using MFe2O4-Based Magnetic Ionic Liquid Effervescent Tablets Consisting of Accessory Functional Fillers

Enhanced extraction of organophosphorus pesticides from fruit juices using magnetic effervescent tablets composed of the NiFe2O4@SiO2@PANI-IL nanocomposites

“…6A). The Na 2 CO 3 + TTA tablet, composed of 212 mg of Na 2 CO 3 , 300 mg of C 4 H 6 O 6 and 15 mg nanocomposites, produced a vigorous effervescence intensity and reaction time ($4 min), consistent with previous results obtained by Ding et al 30 and Wu et al 31 Given its superior performance, the Na 2 CO 3 + TTA tablet was selected as the acidic/alkaline source in preparation of magnetic effervescent tablets.…”

“…Effervescent tablets are composed of three main components: acidic salt, alkaline salt and extractant/adsorbent. 23 According to previous reports, 30,31 we tested two conventional acidic salts and two alkaline salts as potential tablet components, Na 2 CO 3 had the highest ER for diazinon (Fig. 6A).…”

Effervescence-Assisted Microextraction—One Decade of Developments

“…On the one hand, the tablet can be prepared only containing the effervescence agents, while the solvent is added in a different step [ 48 , 49 , 50 ]. On the other hand, the tablet can be prepared containing the carbon dioxide source and the solvent, while the sample is acidified for a better effervescence [ 51 ].…”
