Application of cucurbit [6]uril nonporous as a new adsorbent for removal of dyes from aqueous ecosystems
In this study, the removal of congo red and erythrosine as anionic dyes were investigated by using the cucurbit[6]uril nonporous as a new adsorbent. In the proposed mythology, the Batch removal method was applied. In order to obtain maximum removal efficiency, the effects of acidity of solution, adsorbent dusage and contacting time were investigated and optimized. Adsorption experimental data were analyzed using Langmuir and Freundlich isotherm models and the best-fitted data was obtained with the Langmuir model. The maximum adsorption capacity was 128.2 mg g-1 and 95.9 mg g-1 for congo red and erythrosine, respectively. This method was successfully applied for the removal of congo red and erthrosine dyes from Karron and Bahmanshir water river and Persian Gulf water samples.
