摘要: 将谷胱甘肽修饰到有序介孔碳表面，制备了一种谷胱甘肽功能化的有序介孔碳（GSH-CMK-3），采用傅里叶红外光谱、扫描电镜、热重分析等对其进行了表征。GSH-CMK-3具有优良的化学稳定性和热稳定性，对Cd²⁺具有较强的吸附性能，静态吸附容量为87.87 mg/g，吸附动力学符合准二级动力学模型。在顺序注射微填充柱分离富集体系中，以0.006 mol/L硫脲（溶于0.2 mol/L HNO₃）为洗脱剂，洗脱效率为96%。在最佳实验条件下，进样体积为1000 μL，洗脱体积为50 μL时，富集倍数为17.3，以石墨炉原子吸收为检测器，建立了痕量Cd²⁺的分离富集分析方法，测定Cd²⁺的线性范围为0.05~0.20 μg/L，精密度为2.9%（n=13，100 ng/L），检出限为1.9 ng/L（n=7，3σ），对标准物质GBW08608（水中镉、铬、铜、镍、铅、锌成分分析标准物质）中的痕量Cd²⁺的分析结果与标示值无明显差异。

Abstract: A new derivative of ordered mesoporous carbon (GSH-CMK-3) has been prepared by chemical modification and functionalization of ordered mesoporous carbon with glutathione. The composite was fully characterized by means of Fourier transforming infrared spectroscopy (FT-IR), scanning electron microscope (SEM) image and thermogravimetric analysis (TGA). GSH-CMK-3 showed favorable chemical stability, thermal stability and excellent adsorption performance toward Cd²⁺ and a maximum adsorption capacity of 87.87 mg/g was achieved. The adsorption kinetic follows pseudo-second-order adsorption model. In a sequential injection mini-column separation system, 0.006 mol/L sulfourea (in 0.2 mol/L HNO₃) was adopted as eluent and the elution efficiency was 96%. With a sample volume of 1000 μL and 50 μL of eluate, an enrichment factor of 17.3 was obtained. A procedure for on-line selective separation and preconcentration of trace Cd²⁺ was developed by graphite furnace atomic absorption spectrometry. Along with a detection limit of 1.9 ng/L (n=7, 3σ) and a linear range of 0.05-0.20 μg/L, a RSD of 2.9% (n=13, 100 ng/L) was achieved. The method was validated by analyzing Cd²⁺ in a certified reference material GBW08608.
