Environmental Protection has been globally recognized as the essential issues as well as remarkable debates of every countries in the worlds. One of those problems is the water pollution which cause the devastation of any aquatic creatures and human activities. There is a massive source which contribute to the contamination of water but specifically the dyes and pigments from textile industry generates an enormous hazardous chemical directly to the water environment. Therefore, a method, especially photocatalysis is optimal for the destruction of dye color before discharging.
Additionally, the selection of catalyst is also important for the efficiency of the photocatalytic process. Zeolitic imidazolate framework 67 (ZIF-67) is the chosen substance for the laboratory experiment. ZIF 67 is one class of metal organic frameworks (MOFs) which structured by the connection of group of organic linkers and metal ions. With the special properties such as porosity and chemical stabilities, this compound can be applied in many aspects in industry such as sorption, sensing function, medicine and so on.
The main purpose of the final thesis might be divided into two parts. Initially, searching and gathering the necessary information of photocatalysis, metal organic frameworks, zeolitic imidazolate frameworks (ZIFs) and the mechanism of free radicals in order to release a fundamental background of their properties and production. The next part is experimental performance provides the manufacture of ZIF 67, the influence of its chemical to the destruction of dye (congo red) as well as the determination of free radicals through the reaction.
