Cadmium absorbed by algae Gracilaria, the indicators pH, Time, temperature, initial concentration and adsorbent dosage depends metal. In this study, the best pH to attract the most desirable temperature 45°c, 2.5 The initial concentration of metal in 250 ppm , was found. Most of the absorption occurred in the first 50 minutes for the absorption and uptake kinetics The pseudo-second-order kinetic model was adapted. Hmdmayy models Langmvyd And Freundlich were studied. In the end, by the response surface method (rsm) Using the software minitab best conditions Laboratory for cadmium uptake was obtained.
