一种用于水中汞离子的电化学检测方法
By binding mercury ions with a graphene-supported palladium-based metal-organic framework, the activity of oxidase-like enzymes is enhanced, solving the problem of insensitivity of electrochemical detection methods to low concentrations of mercury ions. This achieves high sensitivity and high selectivity for mercury ion detection, making it suitable for on-site detection of mercury ions in water.
