▎ 摘　　要

NOVELTY - A solution containing lead ion concentration detecting method involves utilizing amino graphene and beta -cyclodextrin modified glassy carbon electrode as working electrode and carrying out reduced oxidation testing of a solution of the metal ions by using the working electrode and a square wave stripping voltammetry technique to obtain square wave stripping voltammetry of metal ions. Standard curve of the stripping voltammetry metal ion is detected to give a concentration of lead ions in the solution according to the square wave metal ions. USE - Method for detecting concentration of lead ions in solution. ADVANTAGE - The method enables detecting concentration of lead ions in solution with high sensitivity and low detection limit in simple, sensitive, convenient and rapid manner.
