Background: Eutrophication occurs in lakes and fresh water when total Phosphate (P) concentrations content exceeds 0.1 mg.L-1. Therefore, P- removal is an important procedure for water purification. In the last decades, adsorption is low-cost technology and one of best solutions for water and wastewater purification. Natural Syrian zeolitic ore (NSZO) gets more attention in Syria. Many researchers suggest NSZO as well-surfactant raw material to be used as promising fertilizer, and for removal of heavy metals and ammonium from drink and waste waters. Objectives: This Research aims to characterize NSZO and to study its efficiency in P- removal from water solutions. Methods: In order to identify the main characteristics of NSZO, XRD pattern analysis is carried out to point out main minerals in the natural ore. Batch experiment used to study P adsorption (removal) and factors that affect P- removal by NSZO. Results: XRD data identified Calcite, Quartz, and zeolite as the main components of NSZO, where Analcime and Phillipsite was the main zeolitic minerals. Otherwise, Phosphate sorption may attribute to Fe–OH sites in oxides components of NSZO, considering Fe(III) oxides content (181.4 g.Kg-1). P-removal increases between 100% and 70% as initial P concentration varies from 5 to 60 mg.L-1. Besides, All used adsorption models (Langmuir, Freundlich and Dubinin - Radushkevich) describe well adsorption as favorable mechanism (R2>0.9), other mechanisms like precipitation or even chemisorption may take place quietly slow. Conclusions. NSZO seemed to be a promising material for P- removal from water solutions. It is suggested that NSZO efficiency in P- removal is caused by zeolites, iron oxides and calcite.
