The study describes the functionalization of melamine sponges with graphene and its use as an adsorbent for the microextraction of sulfonamides from food and environmental samples. The graphene-functionalized melamine sponge (GMeS) was prepared by an easy, one-step procedure, which complies with the principles of green chemistry and is proved advantageous over previously described methods. The applicability...
In this study, the modification/loading of melamine sponge with metallic copper sheets (CuMeS) is discussed. The CuMeS is prepared in a fast, singe-step procedure, where concurrent production of copper oxides is avoided. The as-prepared CuMeS is utilized to develop a sensitive and selective sample preparation procedure to extract sulfonamides (SAs) from milk and water samples. The surface of the resulting...
