Abstract :In this study, a high carbon activated carbon was obtained from the sugar beet pulp by carbonizing with concentrated citric acid. The main purpose of this study is to evaluate the obtained catalyst for heavy metal removal in waste water. The adsorption studies of a basic dye Red 198 on the sugar beet pulp insert ignore into journalissuearticles values(SBP); were investigated. Balance and kinetic studies, carbon adsorbents obtained from sugar beet pulp were used for balance and kinetic studies. With carbonization of sugar beet pulp with citric acid was studied to remove Pb insert ignore into journalissuearticles values(II); from Reactive Red 198 dye aqueous solutions. Adsorption in researchswere performed to investigate the effects of solution concentration insert ignore into journalissuearticles values(20-30-40 mg/L);, temperature insert ignore into journalissuearticles values(25,35,45 ° C); and pH insert ignore into journalissuearticles values(3-6-9); on the separation of Reactive Red 198 aqueous solution from beet pulp. Carbon balance adsorbent obtained from sugar beet pulp was done in equilibrium and kinetic studies. Langmuir and Freundlich isotherm models work were done to be appropriate for Reactive Red 198 adsorption. The maximal lead adsorption capacity obtained from Langmuir isotherm at pH 8 and 25 ° C 837.53 mg/g. Adsorption of Pb insert ignore into journalissuearticles values(II); is an endothermic process. The results showed that Reactive Red 198 from the beet pulp is an inexpensive and efficient adsorbent for the removal of aqueous solutions.
