Isotherm and Thermodynamic studies of Removal phenol by molecular sieve MCM-48
Document Type : Research Paper
Abstract
Abstract
Some water and wastewater pollutants cannot be eliminated with traditional treatment methods. This has encouraged workers to focus on high performance and environmentally friendly methods for their removal. The main objective of this study was to evaluate the performance of MCM-48 in phenol removal from water. MCM-48 was synthesized and the effective parameters were evaluated. The results showed that maximum absorption of phenol in optimal conditions 0.3g adsorbent, time equals 30 minutes, pH =6, concentration in 2.5 mg / L at a temperature of 298 K and constant engine speed 300 rpm at about 88 percent. The thermodynamic parameters showed an adsorption process is spontaneous and exothermic. The Langmiur model fitted well the experimental data with a maximum adsorption capacity of 38.02.
