Abstract

In the present study, two-step extraction strategy combining cloud point extraction (CPE) with magnatic-solid phase extraction (MSPE) was once as soon as used for extraction and determination carmine dye . The strategy consists of preliminary extraction of the carmine via way of CPE in the micelles of a non-ionic surfactant Triton X-114; then notably hydrophobic - tetraethyl orthosilicate (TEOS) modified Fe3O4 magnetic nanoparticles (MNPs) are used to retrieve the micellar phase. The principal parameters affecting the effectivity CPE and MSPE techniques and sign enchancment had been examined and optimized. Under the important conditions, the strategy was linear in the range from 10 to 90 µg Kg-1 with the correlation coefficient (R2) of 0.9923 and detection limit of 10.6851 µg g-1, all materials characterized by using SEM, XRD and FT-IR In the present study, two-step extraction strategy combining cloud point extraction (CPE) with magnatic-solid phase extraction (MSPE) was once as soon as used for extraction and determination carmine dye .
