摘要: The adsorption isotherms of phenol from aqueous solution onto adsorbents obtained egg shell (ESA) andpalm (PSA) were investigated. objectives the investigation to understand effect bothadsorbents on pH and study equilibrium adsorbents. ofadsorbent was studied by shaking adsorbent 0.1 1.5 g with 100 ml acidic aqueoussolution for 30 min at room temperature. experiments performed stirring appropriateamount 50 mg/l concentration constant temperature pressure. TheLangmuir Fraundlich models applied experimental data isotherm constants werecalculated using linier regression analysis. results showed that capacity adsorbentsincreases increasing dosage contact time. Also, affected ofphenol, where maximum observed values lower than 9.
