    In this study, trace amounts of manganese ions were extracted using a sensitive, selective, rapid, and simple micro-funnel magnetic stirring-assisted liquid phase microextraction (MF-MSA-LPME) method and determined by flame atomic absorption spectrometry (FAAS). 1-(2-Thiazolylazo)-2-naphthol) (TAN) and 1-octanol were chosen as chelating agent and extraction solvent, respectively. The effective parameters on extraction efficiency such as type and volume of extraction solvent, pH of sample solution, ligand concentration, extraction time, and ion strength ‎were investigated and optimized. Under the optimum form, limit of detection (LOD), relative standard deviation, and the enrichment factor were 0.16 μg L-1, 2.9%, and 252, respectively. The calibration graph was linear over the range of 1-120 μg L-1 with correlation of coefficient r2 = 0.995.The proposed method could successfully determine trace amounts of manganese ions ‎in the real water samples with good accuracy and validity. تفاصيل المقالة
