DETECTION METHOD FOR HEAVY METAL IONS

Provided is a detection method for heavy metal ions that includes the following steps. 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 usingan acid liquid. An electrochemical method is performed to detect concentrations of the target heavy metal ions. 本发明涉及一种重金属离子的检测方法，其包括下列步骤。使废水流经用以吸附至少两种目标金属离子的离子拓印高分子管。冲洗离子拓印高分子管，以移除离子拓印高分子管中的非目标物。以酸液脱附离子拓印高分子管中的目标金属离子。以电化学法检测目标金属离子的浓度。
