| 摘 要： | 用吸附法制备载银竹炭,研究了吸附条件对载银量的影响.结果表明:一定条件下,硝酸银溶液浓度越大,载银量越大;一定浓度、体积的硝酸银溶液中,投入的竹炭量越多,其载银量越小.同时,研究了载银量对吸附能力的影响.结果表明:竹炭载银后,吸附能力有所下降,但仍具有较好的吸附能力.对银在竹炭上的吸附与分布特征研究结果表明:竹炭对Ag+的吸附为混合吸附过程,但主要为还原吸附,银主要分布在外表面和大孔中.

| Abstract: | Silver loaded bamboo-charcoal was prepared by adsorption method.The influence of adsorption conditions on mass fraction of silver was studied.The results showed that the higher the concentration of silver nitrate,the bigger the mass fraction of silver loaded and the bigger the amount of bamboo-charcoal,the smaller the mass fraction of silver loaded in a definite silver nitrate solution.The influence of mass fraction of silver on adsorption capacity was also studied.The results showed that the loaded bamboo-... |
