| Abstract (EN) |
The removal of heavy metals from water is essential for the survival of all living beings, constituting a fundamental entitlement to everyone's well-being. In recent years, researchers have been increasingly studying filter technologies for heavy metal removal. The limitations for removing heavy metals are high energy requirements, expensive chemicals, and difficult shaping control of filters. Thereby, a technique for water filter should be low-cost, easily shape-customized, and low energy requirements. In this study, we are focusing on fulfilling those limitations by interweaving functional materials and 3D printing techniques. We strive to create various multichannel porous structure filters with different internal structure (grid, honeycomb, gyroid) through 3D printing and alter the surface with metal oxide, acting as an adsorbent for the elimination of heavy metals. The effects of the different internal structures on heavy metal adsorbent were investigated. The morphology of filters was obtained with scanning electron microscopy, present the distribution of iron elements coated in filters of all models. The results showed that arsenic removal efficiency correlated with internal structure and showed the highest removal efficiency with the gyroid structure of 87%. This study has demonstrated that this innovative concept could become an affordable alternative for water filter applications with high removal efficiency. |
