Abstract
In recent years, the manufacture of iron nanoparticles has become a concern because of its efficiency in removing several types of contaminants. Pollutants that can be treated with iron nanoparticles include azo compounds, chlorinated solvents, chlorinated pesticides, inorganic anions and transition metals, organic and inorganic pollutants, heavy metals, nitrates, bromides, arsenic, chromium, lead, antibiotics, and dyes. In general, the manufacture of iron nanoparticles is carried out by reducing three/two charged iron with sodium tetra borane, NaBH4. The manufacture of iron nanoparticles using NaBH4 produces toxic by-products in the form of boric acid and hydrogen gas which is flammable or explosive. This study aims to make iron nanoparticles by utilizing scrap iron waste into copperas then reacting it with rambutan peel extract. The method used is to react iron scrap with sulfuric acid to form copperas which is blue-green in color. The resulting copperas were made into a solution and then treated with rambutan peel extract. The resulting black solution was characterized by UV-Vis Spectrophotometry and TEM. The black solution was dried by spray drying and then the powdered iron nanoparticles were characterized by XRD, FTIR, and SEM-EDX. The results showed that iron scrap can be synthesized into ferrous sulfate with 22.09% Fe content. Rambutan peel extract contains a total phenol content of 877.39 ± 16.6 ppm/100 g rambutan peel or equivalent to 441.42 mg GAE/100 g rambutan peel. Iron nanoparticles were successfully made from copperas from iron scrap and rambutan peel extract with the characteristics of having Surface Plasmon Resonance (SPR) at an absorption of 214 nm, particle size of 5-20 nm in solution form and 20-70 nm in powder form. This result can be an alternative for the production of iron nanoparticles, a useful material to prevent environmental pollution.
