KIT FOR MEASURING RESIDUAL EDTA CONCENTRATION IN AMMONIUM EDTA CHEMICAL CLEANING SOLUTION

摘要

The present invention relates to a kit measuring residual ammonium ethylene diamine tetraacid (EDTA) concentration in a cleaning solution in a chemical cleaning process performed using an ammonium EDTA drug to remove rust formed on a surface of a metal equipment contacting with water. The kit in the present method enables measurement performed using a method of analyzing residual ammonium EDTA concentration in a cleaning solution by a complicated process using six test instruments and four types of reagents in a laboratory by a simple process with test instruments of a glass tube kit and two types of pipettes even in a chemical cleaning site; thereby saving manpower, removing temporal error, and additionally rapidly determining whether the ammonium EDTA cleaning solution is injected.
