摘要: A highly selective molecularly imprinted polymer electrochemical sensor for In3+ detection was proposed. ion chelated with alizarin red S to form a complex In-ARS. The used as the template molecule prepare (MIP) based sensor. selectivity of improved significantly due three-dimensional specific structure complex, and complexation ligands metal ions. Moreover, sensitivity proposed by recording reductive current ligand in complex. This technique sensitive quantitative analysis concentrations ranged from 1×10−8 mol/L 2.5×10−7 mol/L limit 4.7×10−9 mol/L. has been successfully detecting real samples.
