چکیده
|
Oryza sativa linnaeus is an important food item all around the world. due to its huge consumption,a large amount of rice husk is generated as agrowaste which can be used for water treatment by adsorption. its adsorption capacity further can be enhanced by chemical medication. in the present study,urea modified rice husk has been used for removing brilliant vital red and murexide form water in an efficient way. after optimizing operating conditions,isothermal and thermodynamical studies were carried out,which showed that maximum adsorption capacity of urea modified rice husk for removing brilliant vital red and murexide dyes were 28.93 and 30.74 mg.g-1. adsorbent characterization was carried out by recording its ft-ir spectra.
