摘要: 建立了离子色谱分离化学发光法同时检测环境水样中痕量间苯二酚和间苯三酚的方法。利用IonPac AS19阴离子交换分析柱进行分离,以50 mmol/L NaOH 作为流动相洗脱待测物质后,再用鲁米诺-K₃Fe(CN)₆化学发光体系在碱性介质中对其进行测定。最佳发光条件为:鲁米诺浓度为6.0×10^-4 mol/L,K₄Fe(CN)₆浓度为0.1 mol/L,K₃Fe(CN)₆浓度为5.5×10^-5 mol/L。本方法分离时不需使用甲醇、乙腈等有机改进剂,环境友好,同时提高了化学发光的强度。采用本方法测定的间苯二酚和间苯三酚线性范围为0.05-1.0 mg/L,检出限(3σ)分别为4.0和4.3 μg/L。对0.1 mg/L的间苯二酚和间苯三酚标准溶液进行11次测定,相对标准偏差(RSD) 分别为0.9%和1.1%。将本方法应用于实际水样中痕量间苯二酚和间苯三酚的检测,结果满意。

Abstract: A novel method was established for the simultaneous determination of resorcinol and phloroglucinol in environmental water samples by ion chromatography with chemiluminescence detection. Using 50 mmol NaOH solution as eluent, resorcinol and phloroglucinol can be well separated with IonPac AS19 column and determined based on the chemiluminescence reaction of luminol and potassium ferricyanide in an alkaline medium.The optimal CL conditions were 6.0×10^-4 mol/L luminol, 0.1 mol/L potassium ferrocyanide and 5.5×10^-5 mol/L potassium ferricyanide. The absence of methanol and acetonitrile in mobile phase made the proposed method more sensitive. Under the optimal conditions, the detection limits (LOD) of resorcinol and phloroglucinol were 4.0 μg/L and 4.3 μg/L, respectively. The method showed good linearity within the range of 0.05-1.0 mg/L. The relative standard deviations (RSD) for 0.1 mg/L resorcinol and phloroglucinol standard solutions were 0.9% and 1.1% (n=11). The method has been applied to the determination of resorcinol and phloroglucinol in environmental water samples successfully.
