Abstract

PURPOSE: To improve the dissolving speed of scale described in the title without generation of NO gas unlike conventional method, by preparing removing agent described in the title by dissolving in water Al nitrate, or ferric nitrate, and sulfamic acid in a prescribed ratio to the nitrate.
CONSTITUTION: In the preparation of a removing agent for calcium oxalate type scale sticked to apparatus or wall etc., aluminum nitrate, or ferric nitrate, and 5W 300mol% sulfamic acid per 1mol nitrate are dissolved in water and is adjusted to a suitable concn., hereby generation of NO, NO2 during the removal of the scale in prevented so as to prevent the precipitation of scale, the corrosion of apparatuses, and the rate of dissolution of scale is improved, the time required for removing scale is reduced.
