• H2O2
• acridine red
• association particle
• resonance scattering

Under the conditions of pH 5.0 HAc-NaAc, 1.6 X 10(-3) mol (.) L-(1) KI-8.0 X 10(-5) mol (.) L-1 Fe2+ -4. 0 X 10-' mol L-1 H2O2-40 mu g (.)mL(-1) acridine red (AR), when there is H2O2, reacts with I- to form I-3(-). The acridine red reacts with IT. to form AR-I-3 ion association molecule. Under the action of the intermolecular and hydrophobic forces, these association molecules automatically aggregate to form (AR-I-3). association particles that exhibit three resonance scattering peaks at 320, 400 and 595 run respectively. The H2O2 concentration in the range of 0.50-16. 0 X 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.
