Investigation of mesoporous carbon materials by magnetic solid phase extraction of selected phthalates from water samples

摘要

In the present work ordered mesoporous carbon materials soft templating-acidic (STA) were applied as adsorbents in magnetic solid phase extraction technique for isolation of selected phthalates from water samples. STA materials were obtained by soft-templating method in acidic environment. Nickel nanoparticles were added on the STA synthesis stage, thus the obtained material acquired magnetic properties. The analysis of phthalates after the extraction was carried out by gas chromatography-mass spectrometry method. Fast and easy procedure was elaborated, obtaining recoveries close to 90% for some phthalates.
