Effect of loading of C-cloth with ethylenediaminetetraacetic acid (EDTA) on the adsorption capacity for the adsorption of several metal cations was studied. The concentration of ions in the solution was monitored using atomic absorption spectrometry. The adsorption isotherm data for the cations were derived at 25 degrees C and treated according to Langmuir and Freundlich models and was found that for most of the investigated cations Langmuir model was more successful. Adsorption capacities determined from Langmuir isotherms. Loading of the adsorbent with EDTA increased the adsorption capacity for the adsorption of all of the investigation ions.
研究了用乙二胺四乙酸（EDTA）负载C布对几种金属阳离子吸附容量的影响。使用原子吸收光谱法监测溶液中离子的浓度。在25℃下获得阳离子的吸附等温线数据，并根据朗缪尔和弗伦德里希模型进行处理，发现对于大多数研究的阳离子，朗缪尔模型更为适用。由朗缪尔等温线确定吸附容量。用EDTA负载吸附剂提高了对所有研究离子的吸附容量。
