A PVC membrane malachite green(MG) selective electrode with high sensitivity was prepared with the ion-pair of malachite green-sodium tetraphenylborate as the electroactive substance,based on a two-dimensional functional material of restricted access media and molecularly imprinted polymers(RAM-MIPs),which could inhibit ion flux of MG,recognize MG specifically,and eliminate the matrix interference.The electrode showed a linear Nernst response in the range of 3.2×10-8~ 1×10-3mol/L with pH 3~pH 7.5 and a slope of 54.2 mV/pC.The low limit of detection was about 7×10-9mol/L.With the better selectivity,precision and accuracy,this electrode was practicable for the analysis of MG in aquatic water and aquatic products.
