Hierarchical porous carbon nanosheets derived from ZIF-on-LDH as coating for solid phase microextraction of polychlorinated biphenyl in beverages.

Due to persistence, high toxicity, and tendency to bioaccumulate of polychlorinated biphenyls (PCBs), accurate detection of their residual levels in environmental and food samples is particularly important. To address the challenges posed by complex…
