چکیده
Synthetic dyes are using extensively in various industries such as textile, leather tanning, plastic, pulp and paper. Since this dyes are mainly toxic and even carcinogenic, discharging dye containing wastewater into the environment generates serious environmental and health consequences. Therefore, in this research investigated and evaluated the removal effect of Reactive Red 120 (RR 120) from aqueous solutions using Albizia lebbec fruit (pod) partical as a low cost adsorbent to decline mentiined undesirable consequences .In past batch adsorption investigations carried out to study various parameters including 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. For analyzing data equilibrium, used from Freundlich and Langmuir isotherm models. It was found that Langmuir isotherm (R2=0.9992 and qm =1.45 mg/g) is well fitted with our data. According to thermodynamic analyzing, the process exothermic and inherent spantaneous that's it: ΔHo=9.75 J.mol-1and ΔSo=38.13 J.mol-1K-1.
