Typical Fe:H2O2 ratios are 1:510 wt/wt, though iron levels < 2550 mg/L can require excessive reaction times (1024 hours). This is particularly true where the oxidation products (organic acids) sequester the iron and remove it from the catalytic cycle. Fenton''s Reagent is most effective as a pretreatment tool, where COD''s are > 500 mg/L.
