Water is the fundamental importance for all living organisms on earth. Among the organic pollutants encountered in water, phenol and its derivatives are important to identify and quantify them. It is because of their detrimental effects on aquatic organisms as well as human being. The use of fast detection technique such as spectrophotometric technique, electrochemical methods, and biosensor have practical implication. Furthermore, the use of hybrid technology can be used to remove phenolic from wastewater etc.
