Adsorption Study of Rhodamine –B Dye on Plant (Citrus Leaves)

The current research includes the adsorption of Rhodmine-B Dye on surface Citrus Leaves using technique UV. Vis spectrophotometer to determine data quantitative at various contact time, ionic strength, PH and temperature conditions. As a function temperatures 25,35,45,55 0C, dsorption phenomenon was examined, results showed that Rhodamine-B leaves rose with increasing (endothermic process). Using NaCl solution concentrations, effect strength has also been studied. Increasing importance shown improve amount citrus constant temperatures.The quantity Rh-B dye adsorbed increased in rang 3-7. Then were subjected practical obtained use isotherms Langmuir, Frendelsh, Temkin. can be isotherm suitable for applies Ferndelsh thermodynamic functions (the change enthalpy, entropy free energy Gibbs) studied, it found process powder are endothermic an automatic process.
