Ozone (O3) could be absorbed by boric acid-potassium iodide (BKI) absorbent solution to produce tri-iodine ion (I3(-)) that react with victoria blue B (VBB) to form the associated particle (VBB-I3)n and exhibited a strong resonance Rayleigh scattering (RRS) peak at 722 nm. Under the chosen conditions, the RRS peak intensity was linear with O3 concentration in the range of 0.2-50 μmol/L, with a linear regression equation of ΔI722=17.9c-45.4 and detection limit of 0.057 μmol/L. Accordingly, a simple, rapid and sensitive RRS spectral method was set up for determination of trace O3 in air, with satisfactory results.
臭氧（O3）可被硼酸-碘化钾（BKI）吸收溶液吸收，产生三碘离子（I3(-)），该离子与维多利亚蓝 B（VBB）反应形成缔合粒子（VBB-I3）n，并在 722nm 处表现出强共振瑞利散射（RRS）峰。在选定的条件下，RRS 峰强度与 0.2-50μmol/L 范围内的 O3 浓度呈线性关系，线性回归方程为ΔI722=17.9c-45.4，检出限为 0.057μmol/L。因此，建立了一种简单、快速、灵敏的 RRS 光谱法测定空气中痕量 O3，结果令人满意。
