| 摘 要： | 研究表明高含量银离子的存在将大大降低活性炭从硫脲体系中吸附金的吸附速率和吸附容量。这主要是由于大量银离子阻碍了金在溶液中的扩散以及金在活性炭上吸附过程的进行 ,同时少量银离子以大分子络合物的形式被吸附并占据了较大的活性炭表面所造成的。

| Abstract: | The investigated results show that the adsorption rate and adsorption capacity of gold on carbon from a thiourea solution are quite low while having plenty of the silver ions in the solution.It is because that the diffusion prosess and adsorption process are retarded by plenty of sliver ions,and minor surface of which adsorped as complex molecule occupy more of the carbon. |
