Magnetic solid extraction of PCBs in the fruit juices based on polyaniline-modified CoFe2O4@Ti3C2 composite

Polychlorinated biphenyls (PCBs) have been known pollutants, which are ubiquitous in various matrix, even in some food products and beverages like fruit juices. It is of great importance to develop efficient and simple method to detect them in such matrix. In this work, an effective magnetic composite integrating the advantages of the magnism of CoFe
