PHOSPHATE

The potential of almond kernel, physically activated by nitrogen/steam, or chemically activated by Mg2+ or bentonite and then by nitrogen/steam, to adsorb phosphate from wastewaters was evaluated. The performance of biochar was studied as a function of initial phosphate concentration, adsorbent dose, contact time and solution pH. The mechanism of adsorption was investigated by carrying […]

The main aim of this study is to determine the physical and chemical properties of biochar synthesized from different materials (straw rice, sawdust, sugar cane, and tree leaves) at different pyrolysis temperatures (400, 600, and 800 degrees C). The physical and chemical properties such as moisture content, water holding capacity, bulk density, and porosity; and […]

The exponential increase in population demands more food to be produced by employing modern technologies. There is a worldwide increase in the use of chemical fertilizers to rapidly enhance the crop yield. Nitrogen is a crucial plant nutrient, and nitrogenous fertilizers are the most widely used fertilizers. However, the high solubility and volatility of commonly […]
