Abstract
A detection method using colorimetric analysis of the present invention includes: providing a first solution in which two materials selected from metal nanoparticles, an oxidizing agent, and chloride ions are mixed; providing a second solution including one other material that is not included in the first solution among the metal nanoparticles, the oxidizing agent, and the chloride ions; preparing a mixture solution by mixing the first solution and the second solution; and testing and measuring a color change of the mixture solution.
