Fenton's reagent - Opis:
- In this studies the influence of the dose and ratio of chemical reagents (Fe2+ and H2O2) on the efficiency of COD removal and changes of BOD5/COD ratio in landfill leachate was analysed. The molar Fe2+/H2O2 ratio was lower than 1 and amounted to: 1:10, 1:5, 1:3, three research series with 1; 2.5 and 5 g/L Fe2+ concentration. A higher efficiency in removing BOD than COD, and therefore the decrease of BOD5/COD ratio in effluent was stated. The efficiency of COD removal from leachate was from 58.34% (Fe2+ 0.5 g/L, Fe22+/H2O2 1:5) to 8.33% (Fe2+ = 0.1 g/L, Fe2+/H2O2 = 1:10), while the efficiency of BOD removal ranged from 62 to 77%. With the molar ratio Fe2+/H2O2 equal 1:5 the BOD5/COD ratio was the largest for each of the analysed Fe2+ doses. The lowest BOD5/COD ratio was observed for the Fe2+ dose 0.1 g/L and molar ratio of reagents 1:3.
