Magnetic nanoparticles (MNPs) were synthesized by using six different plants’ materials including Lingusfrulucidum (leaves), Cherry (leaves), Franxinuschinensis roxb (leaves), Green tea (leaves), Gourd (peel) and Onion (peel). The iron oxide (Fe<sub>3</sub>O<sub>4</sub>) nanoparticles were prepared by mixing ferric sulfate (Fe<sub>2</sub>SO<sub>4</sub>) and ferric chloride (FeCl<sub>3</sub>) solutions at the ratio of 1:2. Then the prepared Fe<sub>3</sub>O<sub>4</sub> nanoparticles were added dropwise to each of the plant extract upto convert the colour of the solution turn into black, and resulting black colour indicates the existence of MNPs. Characterizations of sythesized MNPs has been done by using UV-Vis spectrophotometer, fourier transform infrared spectroscopy (FTIR) and x-ray diffraction (XRD). The ability of prepared MNPs for methyl orange (MO) and crystal violet (CV) dyes removal from aqueous solutions were investigated in this study. MO and CV is the most common anionic and cationic dyes used in factories and consequently mixed with water and pollute the environment. Initial and final concentrations of the dyes were studied by spectrophotometer for each of the MNPs. Removal efficiency (%) and adsorption capacity (mg/mg) has been studied for both MO and CV dyes, as well as time taken for 100% removal of dyes using H<sub>2</sub>O<sub>2</sub> as catalyst also was studied for each MNPs. The experimental result shows that green tea mediated MNPs is more efficient (92.34% for MO and 96.01% for CV), more adsorption capable (7 mg/mg for MO and 9.5 mg/mg for CV) than the other plant mediated MNPs and it also shows faster (2mins for CV and 4mins for MB) nature to 100% removal of dyes with presence of H<sub>2</sub>O<sub>2</sub> as catalyst. |
