Three-dimensional fluorescence patterns demonstrating the removal of soluble organics by Fe₇₀ and liquid chlorine. ((a) Water sampled before chlorine disinfection; (b) water sampled after chlorine disinfection: chlorine dosage = 1.5 mg/L, and reaction time = 30 min; (c) water treated by Fe₇₀: dosage = 0.06 g/L, and reaction time = 10 min; and (d) water treated by Fe₇₀: dosage = 0.06 g/L, reaction time = 20 min.)
