AbstractRecently, the world has directed to find environmentally friendly and clean materials to be used to treat wastes difficult to treat in the traditional way such as dyes. The object of this study was to synthesize iron nanoparticles using black tea extracts in an environmentally sustainable method. Also, it was developed by supporting with bentonite, used to remove Eriochrome blue-black B dyes from synthesis wastewater of textile factory. From the results, it was noted that black tea leaf extract has reduced iron ions to iron nanoparticles at room temperature. Composite iron nanoparticles were characterized using Scanning Electron Microscope (SEM), and Atomic force microscopy (AFM) studies where the diameter of iron nanoparticles was less than 70 nm. This research shows that ferrous nanoparticles can be manufactured using black tea leaf extract as a reducing agent. It also shows better-supported nanoparticles than unsupported. The decolorization efficiency catalyzed BT-NZVI, B-BT-NZVI increased from (14%, 42%) to (48%, 68%) at 180 min of batch processes when the NZVI concentration was increased from 0.5 g/L to 2 g/L respectively.
