| 摘 要： | 将自制合成的三种新型硫脲型螫合纤维素——硫晚棉纤维（CC－TU），氨基硫脲棉纤维（CC－TSC）和二苯硫脲棉纤维（CC－DPTU）应用于钢的吸附性能的研究，采用火焰原子吸收法测定选择了吸附和解吸的最佳条件。在所选择条件下，这些螫合纤维素对钢具有吸附速度快、吸附完全，吸附能力强，解吸容易和洗脱体积小等特点。

| Abstract: | Three new kinds of thiourea - type chelating cotton cellulose, thiourea cellulose, thiosemicarbazide cellulose and diphenylthiourea cellulose, were synthesized in our Lab, and their absorptive characteristics for copper was investigated. Under the optinum conditions for adsorption and elution of copper selected by using fiame atomic adsorption spectrometry, they show rapid, complete, and powerful adsorptivity for copper. The adsorbed copper can be eluted easily with a small volume of eluant. |
