Aromatic compounds are environmental contaminants that are present in large quantities in the environment. The presence of aromatic compounds in populated areas is an issue that must be addressed due to their various harmful effects. Thus, it is beneficial if a method of detection, that may be utilized quickly and cheaply, is designed to test for these harmful aromatic compounds. Paper sensors are a method of detection that fit both these criteria because they are cheap to make and easy to use. In this experiment stepwise-synthesis was utilized to create a paper sensor by forming a diazonium salt onto a prepared cellulose paper. A diazonium salt was synthesized onto the cellulose paper because an azo-dye is formed when a diazonium salt reacts with an aromatic compound. So if the paper with the diazonium salt on it changes color when used in detection, there may be an aromatic compound present. The purpose of this experiment was to create a sensor that utilized a diazonium salt for detection purposes.
