Description

Iron hydroxide Electro-coagulated sludge from the electrochemical processes of textile wastewater treatment plant has recovered and oxidative transformed iron oxides production with heat treatment was produced. Because hematite and magnetite iron oxides can be produce from iron hydroxide, electro-coagulated sludge as iron hydroxide and oxy-hydroxide rich sludge can be used iron oxides source for different applications. Such as for catalyst, medical and commercial applications. Heat treatment of iron hydroxide with a certain temperature range will have an effect on magnetic nature iron oxides formation. Thus, EC sludge as iron hydroxide was used crystallinity nature as well as phase identification. To this experiment, the author intends to use four critical temperature values as a base to examine the phase change by producing different iron oxides (α-Fe2O3, Fe3O4…). X-ray diffraction study using the XRD machine as well as comparative examination with standard references, the international central diffraction data (ICDD) were investigated. The heat treatment from 300 oC to 800 oC have confirmed us the iron oxide formation and at high temperature, the patterns become more crystal formation.
