在碱性条件下，铁氰化钾氧化鲁米诺，产生化学发光，尿酸对该体系的化学发光有显著的增强作用（亚铁氰化钾存在时）。基于此，建立了一种直接测定尿酸的流动注射化学发光分析法。方法的线性范围为２．０×１０－８～５．０×１０－６ ｇ／ｍＬ；检测限（３σ）为６．７×１０－９ ｇ／ｍＬ；相对标准偏差为１．１％（尿酸１．０×１０－７ ｇ／ｍＬ，ｎ＝１１）。用于血清及尿样中尿酸的分析，结果令人满意。
In basic conditions, potassium ferricyanide oxidizes luminol to produce chemiluminescence, and uric acid has a significant enhancement of the chemiluminescence of the system (in the presence of potassium ferrocyanide). Based on this, a direct determination of uric acid by flow injection chemiluminescence analysis. The linear range of the method was 2.0 × 10-8 ~ 5.0 × 10-6 g / mL. The detection limit (3σ) was 6.7 × 10-9 g / mL. The relative standard deviation was 1.1% ( Uric acid 1.0 × 10-7 g / mL, n = 11). For serum and urine samples of uric acid analysis, the results are satisfactory.
