Ведение процесса при повышенной температуре ускор ет пропесс по4The use of the proposed method of cleaning iron-containing waste 1UD provides a reduction in the consumption of reagents by a factor of 10–20 and eases the dosage of reagent, since it disappears and is needed in the mortar unit. In addition, toxic substances do not enter the circulating water p and the purge water, since the reaction product of the NPOs using hydrogen peroxide is water. This contributes to the protection of water resources from contamination by toxic compounds. Conducting the process at elevated temperature accelerates the process by 4
