Abstract

The use of miniaturized sample preparation techniques has increased considerably; the main reason for this is needs for less solvent amounts than conventional extraction techniques. Among them stand out solid phase microextraction (SPME), stir bar sorptive extraction (SBSE) and microextraction by a packed sorbent (MEPS). However to improve this techniques performance and, also, increase applications, it is necessary the development of new materials with good sorptive properties. Among the materials that has been studied, graphene has a featured position due high superficial area, delocalized electrons-À system and easy functionalization through graphene oxide. For these reason this project intends develop analytical methods that use new lab-made devices using these microextraction techniques with graphene as sorbent. There are few studies using graphene in these microextration techniques, main for SBSE (only two publications found), and without publications in MEPS case. During this work is intended to use as model for evaluation of the new systems, development of methods for determination of benzene, toluene, ethylbenzene and xylenes (BTEX) in underground and streams waters using SPME fibers coated with graphene. Additionally, it is programed methods development for determination of parabens in river and pools waters using SBSE and MEPS using graphene as sorbent.
