Abstract:

A novel, rapid, simple and sensitive dispersive liquid-liquid microextraction method based on the solidification of floating organic drop (DLLME-SFO) combined with high performance liquid chromatography-ultra violet detection (HPLC-UV) was used to determine acrylamide in potato chips. The derivation of the acrylamide happened in the presence of KBr, KBrO3, H2SO4. Based on studies, 1-undecanol was selected as the extraction solvent. The factors affecting the extraction efficiency of DLLME-SFO such as the volume of the extraction solvent, kind and volume of the disperser solvent, effect of concentration of KBr, KBrO3, H2SO4 and time of centrifuge, time of derivative and extraction time were investigated and the optimal extraction conditions were estimated. Under the optimum conditions (extraction solvent: 150µl 1-undecanol;disperser solvent:1000 µl acetone; concentration of KBr, KBrO3:10 ppb; concentration of H2SO4 0.001 mol/l; extraction time: 3min), calibration curve is linear in the range of 0.5-15 ppb and correlation of determination (R2) is 0.993.The method was successfully applied for the determination of acrylamide in the actual potato chips.

Development of dispersive liquid–liquid microextraction solidofied floating organic drop (DLLME SFOD) method for determination of cadmium in biological samples

Introduction: Todays, exposure to heavy metals is happened by being produced in various environmental, industrial processes. The production of metals finally results in air pollution as well as contamination in the food chain. There are harmful effects of heavy metals such as cadmium on different organs. Therefore, this study aimed to identify and quantify cadmium in biological samples using DL...
