Abstract

Background and purpose: Dyes are one of the most contaminants in textile industrial wastewater that are often carcinogenic, mutagenic and non-degradable. Therefore, their removal from effluents is very essential to avoid environmental consequences. The purpose of this study was to gain a better insight into the adsorption process and using an economic technology for dye waste water treatment. For these purposes activated carbon was used. Materials and methods: In this study, the adsorbent surface properties were evaluated using converted Fourierinfera red (FT-IR) test and scanning electronic microscope (SEM). In discontinuous station, adsorbent effectiveness for methylene blue dye removal was measured considering pH, reaction time, adsorbent dose, initial dye concentration and temperature. Finally, data was analyzed using seven kinetic and four isotherm models. Results: The highest removal efficiency of methylene blue was obtained at pH=6, reaction time=180 minutes, and adsorbent dose=2 gl-1. Removal efficiency of methylene blue in initial concentration (50 mg-1) was 91.08. In this study the adsorption process followed the Langmuir isotherm (R2= 0.9971). Also, kinetic studies showed high correlation coefficient on pseudo-second order equation ((R2= 0.996). Conclusion: According to this study, activated carbon from Oak fruit bark could be used as an effective and economic adsorbent in wastewater treatments.
