Generation of multi-functional core-shell adsorbents and simultaneous adsorption of cesium, strontium and rhodamine B |
| 초록 |
We design and synthesize multi-functional adsorbents using a customized needle injector and determine the simultaneous adsorption performance toward hazardous materials, including radioactive cesium (Cs+), strontium (Sr2+) and chemical dye rhodamine B (Rh B). To generate monodisperse multi-functional adsorbents, a tri-functional core is synthesized using a tetrapod needle injector, which is equipped with an aligner and a supporter to align a syringe needles, to rapidly realize a one-step encapsulation of functional reagents including Prussian blue, hydroxyapatite and MXene. Subsequently, a magnetic shell is generated via a chemical co-precipitation process. Results show that the simultaneous adsorption behaviors of the adsorbents toward the three hazardous materials are consistent with Langmuir model. In addition, the adsorbents are separated from the aqueous solution within 5 s by the introduction of external magnetic fields. |
