“…In a second application of LLME to determine As species, a method based on the use of an APDC bonded IL for chelation with As III , followed by conversion of the As III chelated task-specic IL to a hydrophobic IL using KPF 6 as an anionexchange reagent has been reported. 39 Any As V present was reduced to As III using a 2 : 1 w/w blend of KI and Na 2 S 2 O 3 and then the total As was measured using ETAAS. Under optimal conditions, a LDR of 0.2 to 15 ng mL À1 and 0.2 to 20 ng mL À1 were observed for As III and total As, respectively.…”

“…The method was used to analyze the types of As in drinking water and water from the environment, and the results were good. Ashouri et al [ 66 ] developed DLLME using task-specific ionic liquids (TSILs) to extract As. The developed method used an ionic liquid with an ammonium pyrrolidine dithiocarbamate (APDC) bond for chelation with As 3+ , then KPF6 as an anion-exchange reagent to change the As 3+ chelated TSIL into a hydrophobic ionic liquid.…”

Arsenic is a hazardous element that causes environmental pollution. Due to its toxicological effects, it is crucial to quantify and minimize the hazardous impact on the ecology. Despite the significant advances in analytical techniques, sample preparation is still crucial for determining target analytes in complex matrices. Several factors affect the direct analysis, such as trace-level analysis, advanced regulatory requirements, complexity of sample matrices, and incompatible with analytical instrumentation. Along with the development in the sample preparation process, microextraction methods play an essential role in the sample preparation process. Microextraction techniques (METs) are the newest green approach that replaces traditional sample preparation and preconcentration methods. METs have minimized the limitation of conventional sample preparation methods while keeping all their benefits. METs improve extraction efficacy, are fast, automated, use less amount of solvents, and are suitable for the environment. Microextraction techniques with less solvent consumption, such as solid phase microextraction (SPME) solvent-free methods, and liquid phase microextraction (LPME), are widely used in modern analytical procedures. SPME development focuses on synthesizing new sorbents and applying online sample preparation, whereas LPME research investigates the utilization of new solvents.
