| 摘 要： | 在碱性介质中，N-溴代丁二酰亚胺氧化鲁米诺产生化学发光，苯酚对反应具有很强的抑制作用，据此建立了N-溴代丁二酰亚胺-鲁米诺-苯酚化学发光体系测定水中苯酚的新方法。当苯酚的浓度在1.0×10-5～9.0×10-4 mg·mL-1范围内，其浓度与发光强度呈良好的线性关系, 检出限是1.81×10-7 mg·mL-1, 相对标准偏差为1.11%, 将该方法直接用到水样中苯酚的测定, 取得满意的结果。并探讨了该化学发光反应的机理。

| Abstract: | A novel flow injection chemiluminescence method was presented for the determination of phenol. The method is based on the quenching effect of phenols on the chemiluminescence reaction between luminol and N-bromosuccinimide. The linear range for the determination of phenol is 1.0 x 10(-5) -9.0 x 10(-4) mg x mL(-1), and the detection limit is 1.81 x 10(-7) mg x mL(-1). This method was used for the determination of phenol in water samples with satisfactory results. The mechanism of the reaction was also expounded. |
