▎ 摘　　要

NOVELTY - The method involves manufacturing diethylene triamine pentacetic acid (DTPA) functionalized graphene by using graphene oxide prepared Hrnnmer process. A silane reagent is introduced into an amino function preparation graphene. The amino functionalized graphene is used for preparing a DTPA and a DTPA anhydride functionalized graphene. A glassy carbon electrode surface mirror is grinded and polished into an electrode to dry at room temperature. The DTPA acid anhydride is two-ethylene three-amine five-acetic acid two-anhydride. USE - Method for manufacturing a DTPA graphene function modified glassy carbon electrode for a quick heavy metal tracing electrochemical sensor. ADVANTAGE - The method enables achieving quick electrochemical detection of heavy metal trace amount with high sensitivity and wide linear range. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a DTPA graphene function modified glassy carbon electrode. DESCRIPTION OF DRAWING(S) - The drawing shows a graph illustrating a method for manufacturing a DTPA graphene function modified glassy carbon electrode. '(Drawing includes non-English language text)'
