This paper focuses on developing an effective and commercially available adsorbent for cationic dye Safranin (SF). The cationic resin Amberlite ®IRC-50 was chose for this purpose. ®IRC-50 was characterized by Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray spectroscopy (EDX) techniques. The adsorption was optimized under various parameters such amount of support, contact time, initial concentration, temperature, pH. Obtained results show the dye adsorption was rapid during the first few minutes and the rate of removal reached over 97% in first 60 min of adsorbent-adsorbate contact time, then leveled off at 120 min. All results have shown clearly, that ®IRC-50 surface is porous and irregular, which is favorable for an efficient adsorption of Safranin dye molecules. The adsorption modeling through kinetic models showed that the adsorption process follows a pseudo-second order model. The retention mechanism has been identified by different adsorption isotherms.

本文侧重于开发一个有效和commerciall ÿ可用于阳离子染料番红 (SF) 的吸附剂。为此选择了阳离子树脂 Amberlite®IRC-50。®IRC-50 通过傅里叶变换红外光谱 (FTIR)、扫描电子显微镜 (SEM) 和能量色散 X 射线光谱 (EDX) 技术进行表征。在各种参数下优化吸附，例如载体量、接触时间、初始浓度、温度、pH。获得的结果表明，在最初的几分钟内染料吸附很快，在吸附剂-被吸附物接触时间的前 60 分钟内去除率达到 97% 以上，然后在 120 分钟时趋于平稳。所有结果都清楚地表明，®IRC-50 表面多孔且不规则，有利于番红染料分子的有效吸附。通过动力学模型的吸附模型表明吸附过程遵循伪二级模型。保留机制已通过不同的吸附等温线确定。
