Polysulfone/Activated Carbon (PSF/AC) composites in bead form were prepared for Rhodamine B sorption. The scanning electron microscope (SEM) shows that pure PSF bead is smooth surface while PSF/AC bead presents the pore distribution. FT-IR spectra indicate the existence of AC on the PSF/AC bead surface. Under adsorption test of Rhodamine B, it was found that an increase in the AC content in PSF solution results in an increase in the percentages of dye adsorption from 1.38 % to 71.56% for pure PSF bead and PSF/AC added with 4 wt% of AC, respectively.

The composite materials was made using high-viscosity clay as carrier, activated carbon as adsorbent, and titanium dioxide as photocatalyst .The effect of its photocatalytic degradation activity of Rhodamine B was studied. The results showed that the catalytic activity got the maximun at pH of the reaction solution 10, the composite dosage of 5g, calcination temperature of 550°C, activated carbon: titanium dioxide as 0.75:1.

The aim of this work is to prepare the Gelatin/Activated Carbon (GE/AC) composites in bead form using for adsorption of Rhodamine B. The scanning electron microscope (SEM) shows smooth surface and pore distribution for an external and internal GE/AC composite bead, respectively. FTIR-ATR spectra indicate the presence of AC on the GE/AC bead surface. It was found that an increase in the AC content in GE solution from 0.5 to 2.5 wt% resulted in an increase in the percentages of dye adsorption of GE/AC bead from 13.79 to 52.87%. Under the study of equilibrium isotherm it was found that the adsorption isotherm of Rhodamine B follows Langmuir isotherm model. The results indicate that GE/AC adsorbent could be employed for removal of cationic dyes from textile effluent.
