Adsorptive Removal of Aqueous Phase Crystal Violet Dye by Low-Cost Activated Carbon Obtained from Date Palm (L.) Dead Leaflets

Abstract

Up to now, water pollution is still one of the important issues and challenges worldwide, due to its environmental, economic and human life impacts. It is also remains a challenge to environment scientists and technologists. Nowadays, the textile dyeing industry is considered one of the largest water consuming industries and produces large volumes of colored wastewater in its dyeing and finishing process. In this study, date palm tree leaflets (DPL) has been selected as a natural renewable source for the production of a new activated carbon (AC) utilized for the removal of crystal violet (CV) from water-dye system using a batch mode technique. The experiments studies were carried out at different initial dye concentration, contact time, adsorbent dose, and pH. The sorption exhibited high efficiency for CV adsorption and the equilibrium state could be achieved in 30 minutes for the different CV initial concentrations. CV removal was proved to increase with the increase in ACDL dose, pH, and contact time. Agitation rate and total volume of the reaction mixture were kept at 200 rpm and 20 mL respectively. The applicability of Langmuir and Freundlich isotherm equations was investigated and it was found that experimental data fitted very well to both Freundlich and Langmuir models. The maximum adsorption capacity (qm) was found to be 36.63 mg/g.
