Abstract: Provided is a detection method for heavy metal ions that includes the following steps. A waste water is flowed through an ion-imprinted polymer tube for adsorbing at least two kinds of target heavy metal ions. The ion-imprinted polymer tube is rinsed to remove a non-target object from the ion-imprinted polymer tube. The target heavy metal ions in the ion-imprinted polymer tube are desorbed by using an acid liquid. An electrochemical method is performed to detect concentrations of the target heavy metal ions.
