Application of Pistacia atlantica Leaves Powder as Natural Material To Remove Nitrate and Phosphate Ions From Domestic Wastewater by Characterization, Bio-removal, Phytotoxicity StudiesObaida Alhajali1* , Adnan Ali-Nizam1 Rasha Almostafa2 1Damascus University, Department Plant Biology, Damascus, Syria.2International University for Science Technology, General Analytical Chemistry, Syria. Abstract: Description leaves powder using scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), Energy-dispersive X-ray (EDX), specific surface area according to nitrogen adsorption (SBET) methylene Blue (MB), point zero charge determination (pHpzc). A series batch tests were conducted study effect various factors (plant powders dose, contact time, temperature, pH) on the percentage nitrate phosphate removal from domestic wastewater. The kinetics, regeneration ability test plant powder, phytotoxicity treated water spent germination studied. Results SBET analysis showed that have a low microscopic pores, SEM images revealed rough surfaces with uneven cavities, EDX there are high percentages carbon oxygen, good nitrogen, few potassium, calcium, magnesium, phosphorous, sulfur chlorine, FTIR more than five distinct absorption peaks. maximum value was 76.47% 52.20%, respectively, at dose 2 g/L, temperature 25 °C, pH 5, increased increasing time until equilibrium reached after 120 min 180 phosphate, It found ions follows kinetics reaction pseudo-second-order model, can be Regeneration used two successive cycles slight decrease in efficiency. Germination Lepidium sativum indicate no phytotoxicity. That is, is one natural products effective removing
