| 摘 要： | 研究了氨基硫脲纤维对金属离子Pb2+、Ni2+、Co2+的吸附容量、吸附动力学、等温吸附等静态吸附性能以及影响吸附的因素。试验结果表明该纤维对这3种金属离子具有选择性吸附能力,等温吸附在试验浓度范围内符合Freundich方程,氨基硫脲与金属离子之间形成了离子键和配位键,化学吸附起主导作用。

| Abstract: | The thiosemicarbazide-cellulose was prepared and its static adsorption properties such as capacities,kinetics and isotherm for Pb~2 ,Ni~2 ,Co~2 were studied.The factors to influence adsorption process were also investigated.The results indicated that the thiosemicarbazide-cellulose has selected adsorption property to Pb~2 ,Ni~2 ,Co~2 .The adsorption isotherm approximately fit the Freundlich equation within the range of experimental concentration.The ion bond and the conjugant bond were formed between the thiosemicarbazide and Pb~2 ,Ni~2 ,Co~2 .The chemical adsorption was dominant. |
