A multiple model approach for evaluating the performance of time-lapse capsules in trapping heavy metals from water bodies

Adsorption by ion-exchange resins has been widely used as a cost-effective method for removing numerous hazardous materials, particularly heavy metals, from aqueous solutions. For effectively detecting the illegal discharge of industrial wastewater containing heavy metals, we developed "time-lapse capsules" to trap metallic ions from water bodies. Despite recent progress in the development of time-lapse capsules, a fundamental understanding was...
