Bull Environ Contam Toxicol 2019 Apr 11;102(4):560-566. Epub 2019 Mar 11.

Department of Chemistry, North Tehran Branch, Islamic Azad University, Tehran, 1651153311, Iran.

A fast, green and low cost method for analysis of acrylamide in tap and well water has been presented for the first time using solvent terminated-dispersive liquid liquid microextraction (ST-DLLME) with a simple equipment which does not need centrifugation step followed by GC-FID. The use of one variable at a time optimization method revealed that methanol and octanone were the superior disperser and extraction solvents, respectively. A central composite design (CCD) as a response surface methodology was used for multivariate optimization of five independent factors (volumes of extraction and dispersive solvents, pH, salt addition and extraction time) on the extraction efficiency.
