| 摘 要： | 研究了４种螯合剂在活性炭上的吸附和解吸特性，并在ｐＨ７，０－７．５范围内对８种元素进行了在二元螯合活性炭柱上的吸附、硝酸反洗及样品分析试验。结果表明，本富集材料适合于野外现场直接富集水质中８种痕量元素，富集倍数为１００，变异系数为０．５８％－２．４８％之间，加入回收率在９６．３％－１０５．５％之间，可用原子吸收法分析。

| Abstract: | The characteristics of adsorption and de-adsorption of four kinds of chelating agents on active carbon have been studied. The experiment of adsorption, nitric acid elution and sample analysis for 8 metal elements on the dichelating agent-active carbon in the range of pH 7 - 7. 5 were carried on. The results indicated that the enriched materials were suited for enriching 8 metal elements in nature water. The enriching times is 100, coefficient of variation is between 0. 58 and 2. 48 and average recovery is from 96. 3 to 105. 5. The elements can be determined by atomic absorption spectroscopy. |
