| 摘 要： | 建立了测定5-磺基水杨酸的流动注射化学发光新方法。 研究了影响化学发光强度的因素，并初步探讨了可能的发光机理。 在最佳化学发光条件下，化学发光强度与5-磺基水杨酸浓度在5.0×10-8~2.0×10-5 mol/L范围内呈良好的线性关系，检出限为1.0×10-8 mol/L，对5.0×10-6 mol/L的5-磺基水杨酸平行测定9次，其相对标准偏差为2.7%。 该法可用于强力霉素废水中5-磺基水杨酸的测定。

| Abstract: | A new flow-injection chemiluminescence method for the determination of 5-sulfosalicylic acid was proposed. Various factors affected the chemiluminescence signal were investigated and the possible mechanism was also studied. Under the optimum conditions, the linear range for the determination of 5-sulfosalicylic acid was 5.0×10-8~2.0×10-5 mol/L with a detection limit(S/N=3) of 1.0×10-8 mol/L. The relative standard deviation was 2.7% for 5.0×10-6 mol/L 5-sulfosalicylic acid solution in nine repeated measurements. The method was successfully applied to the determination of 5-sulfosalicylic acid in the waste water of doxycycline. |
