Outline of Final Research Achievements

Novel floating-sinking particles containing adsorbents were developed for the efficient removal of contaminants, focusing on fluoride and dyes, from waste water. These particles are engineered with a core component that enables autonomous flotation and sinking, complemented by a multilayered structure featuring an adsorptive and recovery-capable shell. The innovative design of these particles allows for enhanced adsorption efficiency and recovery rates, those of conventional water purification materials. These particles can use without electricity. The versatility of these particles is further demonstrated through the ability to customize the shell component to meet specific application requirements, making them suitable for a wide range of water purification applications.
