Abstract

A novel approach was taken using the bamboo root transformed into activated cellulose, implying dilute nitric acid as the agent activator. The activated bio-sorbent was applied for Iron(II) (Fe(II)) adsorption in batch mode. Then, biosorbent characterization was established using infrared spectroscopy and a scanning electron microscope (SEM). The effect of acid variation, iodine number, contact time, particle size, temperature, and concentration on the Fe(II) adsorption was determined in the batch method. The Freundlich and Langmuir isotherm were analyzed for determining the isotherm of adsorption. The Langmuir model of adsorption is the most suitable for illustrating Fe(II) adsorption. The optimum adsorption capacity occurred at the bio-sorbent particle size of 50 µm, contact time of 300 minutes, a temperature of 50˚C, a pH of 5, and 150 ppm. The bamboo roots have been applied to remove Fe(II) from wastewater, and the recovery% shows 100%. Comparative studies were analyzed with some bio-sorbents for further development. It is hoped that this novel alternative can be applied as bamboo is abundant in Indonesia and many countries in Asia regions.

一种利用竹根纤维素的新方法:从废水中去除铁(ii)的替代方法

采用稀硝酸作为活化剂，将竹根转化为活化纤维素。将活性生物吸附剂应用于铁(II) (Fe(II))的间歇吸附。然后，利用红外光谱和扫描电镜(SEM)建立了生物吸附剂的表征。采用间歇法测定了酸、碘量、接触时间、粒径、温度和浓度对Fe(II)吸附的影响。采用Freundlich和Langmuir等温线测定吸附等温线。Langmuir吸附模型最适合描述Fe(II)的吸附。吸附性能最佳的条件为:吸附粒径为50µm、接触时间为300 min、温度为50℃、pH为5、浓度为150 ppm。用竹根对废水中的铁(II)进行了脱除，回收率达100%。并与几种生物吸附剂进行了对比研究，以期进一步开发。由于印度尼西亚和亚洲许多国家的竹子资源丰富，希望这种新的替代品能够得到应用。

期刊介绍： RASĀYAN Journal of Chemistry [RJC] signifies a confluence of diverse streams of chemistry to stir up the cerebral powers of its contributors and readers. By introducing the journal by this name, we humbly intent to provide an open platform to all researchers, academicians and readers to showcase their ideas and research findings among the people of their own fraternity and to share their vast repository of knowledge and information. The journal seeks to embody the spirit of enquiry and innovation to augment the richness of existing chemistry literature and theories. We also aim towards making this journal an unparalleled reservoir of information and in process aspire to inculcate and expand the research aptitude.
