Abstract
The aim of this study is to compare the adsorption capacity of Remazol Brilliant Blue R (RBBR) onto three different coal-based adsorbents namely, untreated bottom ash (BA), H2O2-treated BA and physical-activated BA. The removal of RBBR was determined over a concentration range of 50-500 ppm using batch adsorption experiment at room temperature. The percentage removal of RBBR was decreased with the increase of initial concentration. The comparison of percentage removal of RBBR onto the various adsorbents followed the trend: physical-activated BA >; H2O2-treated BA >; untreated BA. In addition, the adsorption isotherm constant reveals that physical-activated BA gives the highest adsorption capacity of RBBR. Result shows that the adsorption mechanisms of RBBR onto the adsorbents studied are well presented by both Langmuir and Freundlich isotherms.
本研究的目的是比较Remazol Brilliant Blue R (RBBR)在三种不同的煤基吸附剂上的吸附能力，即未经处理的底灰(BA)、h2o2处理的BA和物理活化的BA。在50 ~ 500ppm的浓度范围内，采用常温间歇吸附法测定了RBBR的去除率。RBBR去除率随初始浓度的增加而降低。不同吸附剂对RBBR去除率的比较结果显示:物理活化BA >;h2o2处理BA >;未经处理的英航。吸附等温线常数表明，物理活化BA对RBBR的吸附能力最高。结果表明，Langmuir等温线和Freundlich等温线都很好地描述了RBBR在吸附剂上的吸附机理。
