Rapid preparation of expanded graphite by microwave irradiation for the extraction of triazine herbicides in milk samples.

In this study, we proposed a rapid and efficient method for the preparation of the expanded graphite (EG). The exfoliation process was accelerated by microwave irradiation, and the preparation time was greatly shortened. The obtained EG was worm-like in shape and exhibits well exfoliated structure. It was successfully applied as solid-phase extraction (SPE… CONTINUE READING
