Adsorption of Rhodamine–B Dye from the aqueous Solution by using Tectonagrandis Bark Powder

Present study we reported the removal of Rhodamine-B from its aqueous solution by adsorption on Tectonagrandis bark powder charcoal using with batch technique and various experimental parameters such as contact time, temperature, initial pH, initial dye concentration at initial pH of 6 and initial dye concentration were carried out by taking 2.52 to 25 ppm. The adsorption dose increasing with 5 to 30 mg/l, removal effecting was found to increasing adsorbent dosages, the adsorption followed first order reaction and adsorption rate model has been developed. The experimental data have also been studied in Langmuir and Freundlich, adsorption equilibrium data fit with most of first order.
