The removal of toxic nickel metal ions by adsorption, using powder activated charcoal (PAC) and non-conventional adsorbent modified Indian powder babhul bark (PBB), was studied at room temperature. The adsorption isotherms were obtained in a batch reactor. It is observed that, the process of uptake followed first-order adsorption rate expression and obeyed Langmuir and Freundlich models of adsorption. Effects of variations in parameters such as pH, contact time, adsorbent dose, initial Ni(II) concentration and particle size were also studied.
在室温下,研究了使用粉末活性炭(PAC)和非常规吸附剂改性印度粉末儿茶树皮(PBB)通过吸附去除有毒镍金属离子的情况。在间歇式反应器中获得了吸附等温线。观察到,吸附过程遵循一级吸附速率表达式,并符合朗缪尔和弗伦德利希吸附模型。还研究了诸如pH值、接触时间、吸附剂剂量、初始Ni(II)浓度和粒径等参数变化的影响。
