Description: Encapsulation of the Fe NPs was synthesized by tea extract and dispersed within sodium alginate beads (Fe-SA-B), and used the degradation of malachite (MG). The results showed that a 92.3% of MG was removed using Fe NPs encapsulated sodium alginate beads (SA-Fe-B), while only 52% of MG was removed by free Fe NPs. Kinetics studies showed that a pseudo-second-order model well described the adsorption of MG using SA-Fe-B, indicating initial adsorption of MG onto calcium alginate beads followed by degradation through SA-Fe-B. The reusability of SA-Fe-B showed that the first 3 cycles were degraded about 85% of MG.
