Abstract: It has prepared several stationary phases from the papyrus plant are of three types first type DP phase of dry papyrus, papyrus plant socket by 0.036 M (EDTA) ethylene diamine tetra-acetic acid at pH=10. Second type activated carbon SAC (sulfuric activated carbon) treated by sulfuric acid at ratio 13, PAC (phosphoric activated carbon) treated by phosphoric acid at ratio 13. Third type modification activate carbon OSAC (oxidized sulfuric activated carbon) and OPAC (oxidized phosphoric activated carbon) modified by nitric acid at ratio 110. The study of effects from different pH value (2 6), contact time (5 180) min, initial concentration (5 600) mg/L, temperature (298 318) K and adsorbed dosage (0.025 0.2) g. The samples characterized using Scanning Electron Microscope (SEM) and Fourier Transform Infrared (FTIR) Spectrophotometry before and after adsorption. suggesting that the Langmuir isotherm fits better with the experimental data, Langmuir model is much higher than that from Freundlich and the practical adsorption.
