Evaluation of Biochar Derived from Partial Pyrolysis of Chara Algae for Adsorption of Lead and Copper from Aqueous Solutions Saja A. Ismael, Salah N. Farhan Diyala Journal of Engineering Sciences, 2025 This study aimed to evaluate the efficiency of biochar (BC) produced from Chara algae via semi-anaerobic pyrolysis as an adsorbent for removing lead (Pb²⁺) and copper (Cu²⁺) ions from aqueous solutions in a batch system. The preparatory process involved washing the algal biomass with tap water and deionized water, followed by a two-stage drying process: solar drying (48 h) and then thermal drying (75°C, 24 h). Dried sample was then ground into fine particles (250–400 μm) and subjected to a semi-anaerobic heat treatment at temperatures between 400 and 600°C for 50 min to adjust the physicochemical properties of the biochar. The adsorption performance was studied under a range of operating conditions, including a range of pH (2–6), contact time (10–150 min), initial heavy metal ion concentrations (20–100 mg/L), temperatures ranging from 25 to 80°C, and various adsorbent concentrations (0.1–3 g/L). The adsorbent was characterized using advanced analytical techniques. Fourier transform infrared spectroscopy (FTIR) was used to identify the functional groups active in adsorption, scanning electron microscopy (SEM) to analyze the surface structure, and energy-dispersive X-ray spectroscopy (EDS) to determine the elemental composition and confirm metal adsorption. Under best conditions (pH 6, dosage 1.0 g/L), the maximum adsorption capacities recorded were 322 mg/g for Pb²⁺ and 196 mg/g for Cu²⁺. The dynamic adsorption studies further confirmed the removing heavy metals from aqueous media, indicating its promise for scalable water treatment. applications.

Copper and lead ions removal from aqueous solution using MgO, nanostractured MgO Salah N. Farhan, Anees Abdullah Khadom, Abdul Mun'em Abbas Karim Applied Chemical Engineering, 2020 This study investigated elimination of Cu+2 and Pb2+2 from prepared stock solutions using MgO, nanostructured MgO sorbents. The maximum cumulative values for copper and lead were 410, 200, 494.9, and 214.6 mg g-1, for nanostructured MgO, MgO, respectively. Freundlich and Langmuir models describe the sorption equilibrium isotherms. Freundlich model gives the best interpretation for experiment data for these ions.The most adequate model describing the kinetic with the experimental data using MgO, nanostructured MgO was a first-order kinetic model. Nanostructured MgO probably has an efficient way to remove metal ions due to its high capability to adsorb these ions.
Monitoring Water Quality Parameters of Khirisan River in Iraq Yaser Ibrahim Jasem, Qassem H. Jalut, Salah N. Farhan, Muataz H. Ismael Journal of Advanced Research in Fluid Mechanics and Thermal Sciences, 2020 In this work, a set of physical, chemical and biological parameters were analysed for Khirisan river from the period extending from December 2017up to November 2018. The samples were selected from three different sites, agricultural, commercial and residential area to assess the water quality of the river for drinking and irrigation purposes. The study showed that a number of diversity factors were recognized which have a direct effect on the quality of Khirisan river. This includes the catchment feeding area of the river, untreated domestic sewage from the restaurants, cafeterias and government buildings which are adjacent to the river. Water quality of Khirisan river, according to the Iraqi and international standards, satisfies the limits of the rules of the drinking purposes for all studied parameters except the values of calcium ions and total hardness value for some rainy months as well as to organic load. The mean values of BOD5 and COD for the three sites were 7.7 and 36 mg/l. In terms of irrigation purposes, the water quality of the river can be considered low to medium damage in terms of salinity and sodium hazards. In terms of chloride risk, there are no toxicity problems to the roots and leaves of the plants. Therefore, it requires a continual intensive water quality monitoring program to reduce its impact.

Statistical Investigation as a Tool for Corrosion Data Explanations and Forecasting of Reliable Operating Regions Muataz H. Ismael, Adiba A. Mahmmod, Salah N. Farhan, Anees A. Khadom, Hameed B. Mahood Chemistry Africa, 2019 The research reports the results of the corrosion rate data of mild steel in H3PO4 acid as a function of temperature and inhibitor concentration. Potassium iodide was used as a corrosion inhibitor. The weight loss technique was used to evaluate the corrosion rate data. Mathematical and statistical analyses were used to interpret the results. Descriptive statistical analyses showed the distribution of data deviate from normal distribution, which means that most of corrosion rate data were distributed at higher level of inhibitor concentration and lower level of temperature and this preferable case in pickling process. Three mathematical models were suggested to represent the data with high correlation coefficients.
Corrosion of Crude Oil Distillation Column: Kinetics and Mathematical Views Ahmed A. Fadhil, Muataz H. Ismael, Salah N. Farhan, Anees A. Khadom, Hongfang Liu, et al. Journal of Bio and Tribo Corrosion, 2019 Corrosion causes of distillation column were studied using mass loss technique and surface morphology investigations as a function of temperature and time. Local and visual examinations were carried out to estimate the damages. Special autoclave apparatus was designed to simulate the real operating conditions and to obtain the corrosion rate data, while scanning electron microscopy and X-ray diffraction were used for surface morphology. Kinetics and mathematical modeling were also applied to correlate the results. It was found that corrosion rate of carbon steel alloy was increased with the increasing temperature and time. Surface morphology supported the mass loss data, and the damage of steel surface was higher at sever operating conditions. Most of corrosion problems were attributed to the presence of sulfur components in crude oil. The reaction is following the zeroth-order rates.
Corrosion inhibition of steel in phosphoric acid Anees A. Khadom, Salah N. Farhan Corrosion Reviews, 2018 Phosphoric acid has been used in many industrial applications and can be in contact with a lot chemical and petrochemical equipment. Most of this equipment is made of steel alloys that may be damaged because of contact with acid. Corrosion inhibitors can be used for to protect steel alloys against several forms and various environments of corrosion. In this paper, the efficiency and applications of organic and inorganic inhibitors in different environments of phosphoric acid are investigated. More than 40 papers were collected and reviewed. Surveys of the stated works in phosphoric acid environments are documented. It was concluded that organic inhibitors performed as good corrosion inhibitors and are used widely. The use of inorganic inhibitors was limited. Most of studied inhibitors follow Langmuir’s adsorption isotherm, and the mechanism of the inhibition can be ascribed to the mixed effect on cathodic and anodic reactions. The synergistic effect was also addressed in the present work.
