Removal of Chromium (vi) in Aqueous Solution and Industrial Wastewater Using Dry Pods of Prosopis Spicigera
نویسندگان
چکیده
The study involves the batch biosorption process for the removal of Chromium in the aqueous solution using the dried pods of Prosopis spicigera. Factors influencing the biosorption are pH, contact time, adsorbent dose and initial metal ion concentration. Characterization of the biosorbent is carried out to study the morphology by using Scanning Electron Micrograph (SEM). The maximum biosorption occurred at pH 3, contact time 120 min, Biosorbent dose 2 g/l and initial metal ion concentration of 200 mg L -1 . Kinetic models were also described and fit good in Pseudo second order. The equilibrium data was also analyzed using Langmuir and Freundlich isotherms.
