- Abstract
The utilization of Cucumis sativus fruit peel (CSP) as an efficient, copious and eco-friendly adsorbent has been explored as an alternative to expensive activated carbon for the removal of acid red 1 dye from textile wastewater. Batch adsorption method is followed in the present work and various parameters like adsorbent dose, pH, and initial dye concentration are optimized. Adsorption data fit best into Langmuir and D-R isotherm models of adsorption taking into consideration the high correlation coefficients values obtained (0.98381 and 0.97391 respectively). The adsorbent is characterized through SEM and FTIR techniques which identify its porous nature and the chemical groups present on its surface. The maximum adsorption capacity is found equal to 18.76 mg per gram of CSP. The values of K and Qm of the D-R isotherm are found equal to 4.21E-0.7 mol²/KJ² and 2.674 mg/g This study concludes that CSP could be used as a successful low-cost adsorbent in treatment of wastewater polluted with textile dyes.
