Elementary studies were done about selective catalytic reduction of NO from flue gas on magnetic iron oxides with ammonia at low and medium temperatures in a fluidized bed,such as Fe_3O_4 and γ-Fe_2O_3.

Investigation has been made of the effect of added titanium polyphosphates and magnetic ferric oxides on the performance of organic coatings by the electrochemical methods.
