Removal of Remazol Brilliant Blue R (RBBR) by Absorbsion on Zeolit Cuo Catalyst

The pollution caused by dyestuffs has been a serious environmental problem for years. Within the overall category of dyestuffs, Remazol Brilliant Blue R (RBBR) is an anthraquinone dye used in textile industries. This paper concerns study different experimental parameters which affect decolorization efficiency RBBR mixture. Thermal degradation done carried out with 4 mL 10 ppm solution into reaction flask. Added number H2O2 and CuO zeolite catalyst. reactor was heated oil bath glycerin stirred 90 minutes. optimum catalyst weight obtained at 100 mg, able to decrease time 50 minutes compared without percentage removal on this loading 96.26%. micro pores about 20 nm, shows formation nanoCuO particles structure. structural feature may be important since it increases total surface area. diffusion such can explain absorption capacity.
