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 the study of the different experimental parameters which affect the decolorization efficiency of the RBBR mixture. Thermal degradation is done by carried out with 4 mL of 10 ppm RBBR solution into the reaction flask. Added a number of H2O2 and CuO zeolite catalyst. The reactor was heated in oil bath glycerin and stirred for 90 minutes. The optimum catalyst weight was obtained at 100 mg, which was able to decrease the reaction time 50 minutes compared to the reaction without catalyst. The percentage of dye removal on this catalyst loading was 96.26%. The micro pores of CuO zeolite is about 20 nm, which shows formation of nanoCuO particles in zeolite structure. This structural feature may be important since it increases the total surface area. The diffusion into such pores can explain the absorption capacity. |
