| titleOfInvention | Method of determining chelating agent and determination kit for chelating agent |
| abstract | The concentration of a water treating agent can be simply understood on site where thermal equipment is placed. A method of determining a chelating agent according to the present invention includes the steps of: collecting a water sample; adding a first chemical solution containing a metal indicator and a second chemical solution containing a pH adjuster to the collected water sample, respectively; dropping a third chemical solution which contains a metal salt that causes a change in color of the metal indicator into the water sample added with the first chemical solution and the second chemical solution, followed by counting the number of droplets required for the water sample to change color thereof; and determining a concentration of a chelating agent in the water sample on the basis of the number of droplets of the third chemical solution. A kit for determining a chelating agent according to the present invention includes: a first container that reserves a first chemical solution containing a metal indicator; a second container that reserves a second chemical solution containing a pH adjuster; and a third container that reserves a third chemical solution containing a metal salt that causes a change in color of the metal indicator. |
