Abstract:

The aim of the research was to determine the efficiency of decomposition of a nonionic detergent Symperonic NP10 by the Fenton method in the presence of iron nanocompounds and to compare it with the classical Fenton method. Detergent water solutions were subjected to the classical purification method with the application of ferrous sulfate and then compared by using ferrous sulfate with the addition of iron (II, III) oxide nanopowder. The treatment process was optimised from studies on the effect of ferrous sulfate and iron (II, III) oxide nanopowder doses, hydrogen peroxide and pH of the solution on treatment efficiency. Iron oxide nanopowder application allowed to increase the efficiency of detergent decomposition.
