Application of Response Surface methodology (RSM) for the Removal of Nickel Using Rice Husk ASH as Biosorbent
نویسندگان
چکیده
The Rice Husk Ash is a cheap and readily available biosorbent for the removal of nickel ions from aqueous solutions. This investigation comprises of the equilibrium and kinetics study for biosorption of nickel ions from aqueous solutions using Rice Husk Ash powder as a biosorbent in a batch process. The Rice Husk Ash is obtained from a hotel near Andhra University campus, is dried in sunlight for 15 days. The biosorption process is carried out in batch process by varying four parameters: pH, Dosage, Concentration and Temperature of the solution of the process.
