Possibility of Removing Phosphates from Activated Charbon Made from Date Kernels

Phosphates in natural waters and whatever their origin, promote the formation of algae, reduce dissolved oxygen biodiversity aquatic ecosystems. At high doses, phosphate salts can cause health problems. The objective our study was to develop a simple, efficient environmentally friendly sorption depollution technique on available inexpensive media. We have studied adsorption activated carbons prepared from date kernels. Batch tests were carried out order different operating parameters such as effect contact time, pH, initial concentration adsorbent dosage kinetic. equilibrium analyzed by Langmuir, Freundlich isotherms model. Results show that reversible quantity adsorbed reached its maximum value (14.49 mg/g) after 40 minutes. It also found uptake affected variation carbon dosage. improved with an acidic pH (pH = 6), results kinetic studies revealed based kernels (Biocar) intra-particle diffusion involved mechanism. Also, isotherm showed Langmuir best fit data physical type.
