PURPOSE: A cleaning solution for regenerating DE-NOx catalyst using catalyst activation preserver is provided to effectively protect titanium, tungsten, vanadium which are main active components and to remove waste DE-NOx catalyst, calcium, sodium, iron, and sulfur. CONSTITUTION: A cleaning solution for regenerating DE-NOx catalyst using catalyst activation preserver comprises catechol and organic acid. The organic acid is one or more which is selected from a group consisting of acetic acid, lactic acid, citric acid, sulfonic acid, ascorbic acid, and glycolic acid. The organic acid comprises acetic acid and lactic acid. A ratio of organic acid to catechol is 1 : 1. A ratio of catechol to acetic acid to lactic acid is 2 : 1 : 1. 0.0-0.1 wt% of catechol is included. |
