“…While the adsorption capacity was expected to increase with the increase in the amount of adsorbent, on the contrary, a decrease in adsorption was observed. On the one hand, while the amount of adsorbent increased, on the other hand, the amount of BrPB, the species to be adsorbed, was constant and the adsorption capacity decreased because the adsorbent surface became saturated [19][20][21][22]. Considering the values in Equation 2.3.1, it is expected that the adsorption capacity will decrease as the amount of adsorbent increases.…”

In this study, an anionic dyestuff bromophenol blue (BrPB) from the aqueous solution was removed by adsorption in the presence of bentonite (B), zeolite (Z) and graphene oxide (GO). The effects of pH, adsorbent amount, initial concentration of BrPB, temperature and time on adsorption were investigated. After the adsorption process, ultraviolet-visible region spectrophotometer (UV-VIS) was used to measure the amount of dyestuff remaining in the solution which is not adsorbed. It’s found that; the optimum values obtained for the adsorption process; the optimum pH value 5 for B and Z, 4 for GO; 0.03 g amount of adsorbent and 60 minutes for the equilibrium time. The compatibility of Langmiur and Freundlich isotherm models was found as Z> GO> B and GO> B> Z respectively. In terms of kinetics aspect, it was observed that all adsorbents were comply with pseudo-second order reaction kinetics. To be positive of ΔG° value for B and Z is of physical nature of adsorption, to be negative of ΔG° value for GO requires to be chemical nature of adsorption. When the obtained ΔH° values were examined, it was observed that the reaction was endothermic for B and Z and exothermic for GO. The negative value of ΔS° for B and Z adsorbent species indicates that the randomness between solid and liquid decreases, whereas the positive ΔS° value for GO indicates that the randomness between solid and liquid increases. The highest adsorption capacity value obtained after the measurements made under optimum conditions is 589 mg g-1 for GO and 15.7 and 19.8 mg g-1 for B and Z, respectively.

Excessive exposure of human to organic contaminants from industrial effluents calls for the implementation of effective pollutants removal techniques. This article investigates the photocatalytic degradation of bromophenol blue dye using Strontium oxide nanoparticles co-doped with Nickel and Zinc. Hydrothermal synthesis produced the nanoparticles, which were subsequently characterized using various analytical techniques. UV/Visible revealed absorption peaks at 294 nm, 306 nm, 311 nm, and 318 nm, while FTIR spectroscopy identified stretching peaks at 416 cm-1, 588 cm-1, and 856 cm-1 for Ni-O and Sr-O bonds. The nanoparticles displayed diameters ranging from 30.50 nm to 36.97 nm. EDX analysis confirmed the elemental composition, with Sr and O comprising of approximately 82.02 %, and Ni and Zn approximately 3.21%. Photocatalytic degradation experiments demonstrated that SrO nanoparticles 85.42% degradation efficiency, while co-doped SrO nanoparticles achieved an impressive 97.97% degradation efficiency. This work highlights the potential co-doped SrO nanoparticles as a promising solution for the efficient removal of organic pollutants from the industrial wastewater, addressing environment contamination concerns.

“…Water is a fundamental element for sustaining life and serves as a crucial commodity for various sectors such as agriculture, energy production, and manufacturing [ 1 , 2 ]. Nevertheless, the global demand for water is steadily rising due to factors such as population growth, urbanization, and industrialization, resulting in water scarcity in numerous regions across the globe [3] . According to projections by the United Nations, by 2025, approximately 50% of the world's population will be residing in areas where water scarcity is a significant concern [ 4 , 5 ].…”
