Biography :

She has an excellent experience in analytical laboratory instruments; during her postdoctoral stay in California, she had got special experiences in the advanced lab of Peter A Rock Thermochemistry Laboratory and NEAT ORU, University of California at Davis, under the supervision of Professor Alexandra Navrotsky. During her staying at NEAT ORU lab, she measured the interface enthalpy of nanocrystalline silver(I) oxide (Ag2O.nH2O). she synthesized Ag2O.nH2O nanocrystalline samples of varying surface areas and degrees of agglomeration by wet chemical technique. Moreover, she tried to find a new analytical approach to determine oxidation states in complex refractory oxides containing iron, uranium, cerium and other mixed valence cations. Using titrimetry method, which is rarely applied to refractory oxides and pure metal powders because of their low solubility in water. During her work at the laboratories of the University of Jordan, her researches in the field of wastewater and water treatment focus in using different low-cost, natural adsorbents from the Jordanian local environment. I studied the adsorption isotherm of humic acid onto local kaolinite clay using different isotherm models, trying to explore the effects of humic acid concentration, pH, and temperature during this process. Kinetic, equilibrium and thermodynamic studies of adsorption of some heavy metals from aqueous solution onto modified adsorbent were also investigated using both batch and column techniques. Currently, she has extended her research direction toward the corner of antibacterial nanocomposite polymeric membrane based water filter.

Research Interest :

- wastewater and water treatment - synthesis nanocomposite polymeric membrane based water filter.
