Based on typical Fenton reaction,a specific kind of triphenylmethane dyestuff,chlorophenol red was developed to be a colorimetric chemosensor for Fe~(2+),and its sensing behavior toward metal ions was further investigated by UV-Vis spectroscopy.The results obtained showed that CPR exhibited high selectivity for Fe~(2+) over other metal ions.In the presence of H_2O_2,the addition of Fe~(2+) made the absorption peak of 435nm descended with a distinct color change of the CPR solution from yellow to colorless.After the necessary condition as well as the spectrophotometric properties of the sensing system was explored in detail,we suggested CPR a new colorimetric chemosenser for the rapid,easy,and highly selective detection of Fe~(2+) in solution.
