Název v původním jazyce

In-syringe magnetic stirring-assisted dispersive liquid-liquid microextraction for automation and downscaling of methylene blue active substances assay

Popis výsledku v původním jazyce

A simple and rapid method for the determination of the methylene blue active substances assay based on in-syringe automation of magnetic stirring-assisted dispersive liquid-liquid microextraction was developed. The proposed method proved to be valid forthe determination of anionic surfactant in waste, pond, well, tap, and drinking water samples. Sample mixing with reagents, extraction and phase separation were performed within the syringe of an automated syringe pump containing a magnetic stirring barfor homogenization and solvent dispersion. The syringe module was used upside-down to enable the use of chloroform as an extraction solvent of higher density than water. The calibration was found to be linear up to 0.3 mg/L using only 200 mu L of solventand 4 mL of sample. The limits of detection (3 sigma) and quantification (10 sigma) were 7.0 mu g/L and 22 mu g/L, respectively. The relative standard deviation for 10 replicate determinations of 0.1 mg/L SBDS was below 3%. Concentration
