چکیده
toxicity, cancinogenic activity, and mutagenicity. The purpose of this study was evaluation of the removal of Reactive Red 120 (RR-120) dye from aqueous solution by date Palm (Phoenix dactylifera) seed particles. Batch adsorption studies carried out to study various parameters included contact time, initial concentration of Reactive Red 120, pH, and adsorbent dosage. The concentration of dye was measured using a UV-vis Spectrophotometer at the wavelength of 520 nm. Freundlich and Langmuir isotherms were used to analyze the isotherm. it was found that Langmuir isotherm (R2=0.9991 and qm =1.68 mg.g-1) is well fitted with our data. According to Thermodynamic analysis, the process exothermic and natural (ΔHo= -0.006 J.mol-1 and ΔSo= -13.9 J.mol-1K-1). To evaluate the mechanism of adsorption, pseudofirst order and second order kinetic models were used. The adsorption mechanism was found fit the second order (K2= 0.4 mg.g-1.min-1 and R2= 0.999).
