Water pollution can be defined as the contamination of a stream, river, lake, ocean or any other stretch of water, depleting water quality and making it toxic for the environment and humans. The environmental effects of water pollution primarily involve the damage that pollution does to the surrounding ecosystem. Many of the organisms that depend on a supply of relatively healthy water will die. This work investigates the removal of copper ions from simulated wastewater by electrocoagulation EC, in which the impact of initial copper concentration, initial pH solution, and the temperature was made. These investigations used the Box-Behnken experimental design (BBD), combined with response surface methodology RSM. The results show that the removal efficiency ranged between 26 and 97%; optimum conditions for the highest removal efficiency are 99.37% at 56 °C, 3 and 200 ppm for temperature, initial pH solution, and initial copper concentration, respectively. According to the analysis of variance ANOVA, the correlation coefficient R2 is 99.1%, proving that the experimental data and model predictions agreed well via high adj. R2 (97.48%).

The model fuel (Heptane contained 2500 ppm from DBT) was desulfurized electrochemically at a constant current (300 mA), in which the process consists two steps; the first step is electrochemical desulfurization by using an electrochemical cell contains two graphite electrodes immersed in electrochemical cell; the cell contains model fuel, hydrogen peroxide as oxidation agent, 0.106 M is NaCl to enhance electrolyte electrical conductivity. The investigation was at different operation parameters; temperature range (40-50-60 °C), stirring time (10-20-30-40-50) min, while the second step is extraction with acetonitrile. The results show final sulfur concentration decreased when increasing time at the same temperature for example. Kinetics parameters calculation shows that electrochemical desulfurization ECD reaction follows pseudo 1st order reaction, the rates constant of reaction are 0.0175, 0.0191 and, 0.0193 at temperatures 40, 50, and 60 °C, respectively, while activation energy equal 4.433 kJ/mol.

In this study, the catalyst activity of Fe2O3 supported on Graphene for Iraqi gas oil oxidation desulfurization (ODS) by hydrogen peroxide (H2O2) was investigated. The prepared catalyst was synthesized by wet impregnation for ferric nitrate as a Fe2O3 precursor while Graphene represented as catalyst support. The synthesized catalyst was characterized by XRD, FTIR, and EDS analysis. The experiments were designed according to three-level for three variables by Box-Behnken experimental design; Stirring time, catalyst dosage and temperature while the sulfur removal efficiency acts as experiment response. Catalyst activity was studied by ODS reaction for Iraqi gas oil (sulfur content 9400 ppm) at temperature range (40-60 ºC), stirring time (160-240 minutes) and catalyst dosage (0.5-2.5 g), the results show maximum sulfur removal efficiency 90% at stirring time, catalyst dosage and temperature 240 min, 1.5 g, and 60 ºC, respectively. ANOVA analysis shows the important effect of each independent variable on sulfur removal efficiency (response) as following influential order; stirring time, reaction temperature and catalyst dosage. Kinetics calculation showed that the ODS reaction obeys pseudo first-order reaction with reaction rate constant equal 1.0837, 1.5893, and 2.5053 at temperature 40, 50, and 60 ºC, respectively, while activation energy equal 36.26 kJ/mol.
