Fawell, United Kingdom, to whom special thanks are due. The chemical properties of the solution, such as pH, coexistent anions and ion strength, have great influences on the Drinking water oxidation and disinfection processes The results indicated that chlorite, chlorate and perchlorate had a good linear correlation in the corresponding mass concentration range and the linear correlation coefficient was >0.999. This is done through addition of soluble solid chemical compounds such as calcium chloride and calcium hypochlorite or liquids chemical compounds such as sodium hypochlorite and bleach or gaseous chemical compounds such as chlorine and chlorine dioxide [1-4]. Although these compounds have been fou… Appl Calibration plots for chloride, chlorate and chlorite standards.
