▎ 摘 要
NOVELTY - Method for detecting heavy metal involves adjusting pH of sample solution to 3-7, depositing the sample solution on sensor including electrode and graphene oxide-coated polymer obtained by electrolytically-polymerizing pyrimidyl aminothiophene monomer. USE - Detection of heavy metal e.g. zinc, cadmium, lead, copper and mercury (all claimed). ADVANTAGE - The method enables efficient detection of heavy metal using sensor having high sensitivity with respect to heavy metal.
