In this work, we report the adsorption studies of dyes using as-prepared doped poly(3,4-ethylenedioxythiophene) (PEDOT). The conjugated polymer PEDOT was prepared by the solid-state polymerization method and used as an effective adsorbent for the removal of various dyes from aqueous solution. It was found that the as-prepared PEDOT adsorbs selective anionic dyes, whereas no significant adsorption was observed for cationic dyes. The effect of concentration of eriochrome black T (EBT) dye on time-dependent adsorption was studied. Like doped PEDOT, de-doped PEDOT was examined with different concentrations of EBT dye solutions and observed poor adsorption. The adsorption kinetics and isotherms for doped and de-doped PEDOT were studied. The morphology and elemental composition of doped PEDOT before and after adsorption were analyzed by scanning electron microscopy and energy-dispersive X-ray, respectively. Further, the effectiveness of as-prepared doped polymer PEDOT as an adsorbent for EBT dye from organic solvents (ethanol, DMSO, acetonitrile and DMF) was carried out.

在这项工作中，我们使用报告染料的吸附研究原样准备掺杂聚（3,4-乙烯二氧噻吩）（PEDOT）。共轭聚合物PEDOT是通过固相聚合法制备的，可作为一种有效的吸附剂，用于去除水溶液中的各种染料。结果发现作为- 制备的 PEDOT 吸附选择性阴离子染料，而未观察到对阳离子染料的显着吸附。研究了铬黑 T (EBT) 染料浓度对时间依赖性吸附的影响。与掺杂的 PEDOT 一样，用不同浓度的 EBT 染料溶液检查去掺杂的 PEDOT 并观察到吸附不良。研究了掺杂和去掺杂 PEDOT 的吸附动力学和等温线。分别通过扫描电子显微镜和能量色散X射线分析了吸附前后掺杂PEDOT的形貌和元素组成。此外，的有效性作为-prepared掺杂聚合物PEDOT作为用于从有机溶剂（乙醇，DMSO，乙腈和DMF）EBT染料的吸附剂进行了。
