Humic acid (HA) is a component of natural organic matter (NOM) with high molecular weight and complexity. The presence humic in water raises serious concerns due to its toxicity ability form carcinogenic trihalomethanes. Adsorption was shown be an effective method for the removal from various wastewater sources. Many adsorbents were feasible removing HA wastewater, including carbon-based activa...

In this mathematical model, the consequences of Soret and Dufour’s effects on energy mass transport have been reported. The hybrid nanofluid (hnf) comprised silver (Ag) magnesium oxide (MgO) nps is studied over a stretching rotating sheet. influence thermal radiation, second-order chemical reaction, activation energy, magnetic field also applied to fluid flow. phenomena are designed in form non...

Abstract: composition of MgO and nano boehmite. The reactant and potassium chloride, as the reaction media, were fired at800-1000 °C at different dwell times (0.5-5 h) in the ambient atmosphere. After washing and filtration, the spinel nanopowder was characterized by X-ray diffraction (XRD), Scanning electron microscopy (SEM), and Brunauer-Emmett-Teller (BET) techniques. It was demonstrated tha...

The current work focuses on the preparation of magnesium oxide nanoparticles using aqueous chloride salts and sodium hydroxide powder by a simple chemical precipitation method at an annealing temperature 700 °C for 6 hours. structural morphological properties were investigated X-ray diffraction (XRD). Polycrystalline cube Scherer equation showed crystalline size 17.23 nm. EDS analyzes high puri...
