Preparation of Iron Plate
Iron used in this study size 2x4 cm with 1cm thick. Square but thin to allow time to hang it in a test glass.
After the iron is cut to pieces of the size mentioned above, the iron is poured at the end so it can be transported in a test glass containing the extract solution, Hcl, and aquades. Hangers wear a single copper electric cable.
Before use of course iron first sanded by rust on sand paper. Sand paper with numbers 400, 600, 800, 1000, 1200. However, for the first stage if the rust is thicker it is better to use sand paper 150 because the smaller the paper number the more rough it speeds up the amplification process.
Please use hand-strainer on stage iron sandpaper plate. otherwise you will be hurt.
