摘要:
The conventional electrochemical detection in food samples often suffers from low stability and poor reproducibility. The construction of ratiometric sensor is regarded as an effective means to overcome the issues. Herein, poly-curcumin (p-CCM)-Multi walled carbon nanotubes (MWCNTs)-layered double hydroxides (LDHs) was constructed as a novel rationmetric sensing material for detection of Cd2+ and Pb2+ in grain samples. Under the synergistic effect of MWCNTs and the adsorption capacity of LDHs, the p-CCM/MWCNTs/LDHs can significantly enhance the electrochemical responses of heavy metals. In the...
