Abstract:Under the conditions of pH 5.0 HAc-NaAc,1.6×10-3 mol·L-1 KI-8.0×10-5 mol·L-1 Fe2+-4.0×10-6 mol·L-1 H2O2-40 μg·mL-1 acridine red (AR), when there is H2O2,reacts with I- to form I-3. The acridine red reacts with I-3 to form AR-I3 ion association molecule. Under the action of the intermolecular and hydrophobic forces, these association molecules automatically aggregate to form (AR-I3)n association particles that exhibit three resonance scattering peaks at 320, 400 and 595 nm respectively. The H2O2 concentration in the range of 0.50-16.0×10-6 mol·L-1 is proportional to the resonance scattering at 400 nm. And a new resonance scattering spectral method was described for the determination of H2O2 in water samples with satisfactory results.
