“…The growth of industries has played a vital role in advancing society, improving living standards, and driving economic development 1 . However, this industrial progress has come at a cost with the increased pollution of water bodies that poses significant risks to the environment and living organisms 2 . In particular, releasing heavy metal ions into water sources has become a considerable concern and a pressing issue that requires immediate attention 3 .…”

The research focuses on utilizing gamma irradiation to synthesize polyacrylic acid-co-polyacrylamide p(AAm-co-AAc) hydrogels. The effect of synthetic parameters on physicochemical features of p(AAm-co-AAc) hydrogls were examined, including acrylic acid (AAc): acrylamide (AAm) weight ratios, monomer concentration, and gamma irradiation dosage (kGy). At the optimum synthetic conditions (30 kGy and 75% AAc), different chemical modifications are explored to incorporate sulfonate, hydroxyl, carboxyl, cysteine, thiol, and amine functional groups within the bare hydrogel (Cpd 0) structure. Fourier-transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM) analyses confirmed the success development of functionalized hydrogels (namely Cpd 1 to 6) with three-dimensional porous structures. These modified hydrogels include Cpd 1, a sulfonated hydrogel through a sulfonation reaction; Cpd 2, modified via NaOH hydrolysis; Cpd 3, modified using thionyl chloride; Cpd 4, incorporating cysteine modification through reaction with cysteine; Cpd 5, with 4-(Dimethylamino) benzaldehyde; and Cpd 6, modified with 3,4-Dimethylbenzoic acid.The effect of hydrogel composition and surface functionalities on the swelling capacity and interactions with scale-forming/heavy metal ions (e.g., Ba2+, Sr2+, and Cu2+) was investigated in saline water solution (NaCl = 1000 mg/L). Batch adsorption studies reveal that all modified hydrogels exhibited higher removal efficiency for the three metal ions than unmodified p(AAm-co-AAc) hydrogel, validating the key role of surface functionalities in tailoring hydrogel affinity for metal ions adsorption. Amongst these, NaOH-treated hydrogel (Cpd 2) outperformed all other modified ones in the removal of Cu2+, Ba2+, and Sr2+ ions, with maximum capacities of 13.67, 36.4, and 27.31 mg/g, respectively. Based on adsorption isotherm and kinetic modeling, the adsorption process of the three metal ions onto all modified hydrogels better obeyed Freundlich isotherm and pseudo-first-order kinetic models. Thermodynamic studies also indicated that the adsorption behavior of Sr2+ ions can exhibit both exothermic and endothermic characteristics, depending on the nature of hydrogel surface chemistry. Conversely, the adsorption process of Cu2+ and Ba2+ ions onto all modified hydrogels is endothermic, suggesting favorable chemical adsorption mechanisms. These findings reveal that the specific adsorption performance of hydrogel is dependent on the type of modification and the targeted heavy metal ions. Based on the nature of hydrogel surface functionality, surface modifications can change the charge density, hydrophilicity, and overall chemical environment of the hydrogel, offering a versatile approach to optimize the adsorption affinity/selectivity of hydrogel's in removing scale-forming/heavy metals from water solutions.

The use of soil for the production of crop products leads to changes in the natural properties of soils and their natural state. When various situations arise, soil properties can change in different forms and with unequal degrees of severity; a process that worsens quantitative and qualitative properties is defined as soil degradation. The significant role of soil in people’s lives should serve as an incentive for its rational use and to prevent the occurrence of degradation transformations leading to a decrease in its environmental and production functions. The purpose of the research is to assess soil contamination of agricultural lands in the Samara region with insecto-acaricides and herbicides. Objectives: - to establish the average and maximum content of residual quantities of pesticides in soils; - determine the area of contamination with residual quantities of pesticides. The research was carried out in 7 districts (Bezenchuksky, Syzransky, Stavropolsky, Volzhsky, Privolzhsky, Bolshechernigovsky, Elkhovsky) of the Samara region in 2020-2022. To assess soil contamination with residual amounts of pesticides, soil samples were taken in spring and autumn to the depth of the arable layer. In selected soil samples, the residual amount of insectoacaricides (DDT, HCH, HCB, metaphos) and herbicides (prometrin, atrazine, simazine, 2.4-D, trifluralin, THAN, dalapon) was determined. The analysis of contamination of agricultural land in the study region showed that the content of controlled pesticides in soils depended on both the period of soil sampling and the year of research.

Energy is crucial for economic growth and is necessary for the progress of all nations. The demand for renewable energy sources with very low environmental impact and reduction in hazardous gases emission has increased due to the need for sustainable industrial city solutions in energy supply. This study presents a proposed advanced multi-energy-based hybrid system for meeting the electric needs of an industrial belt at Jamnagar industrial city. The proposed system aims to enhance the existing infrastructure by integrating additional energy generation sources, energy storage, and a converter to achieve significant cost reductions. The proposed system comprises a 31 kW PV system, 121 kWh of battery capacity, and 6.0 kW of wind generation capacity. By incorporating these elements, the operating costs are projected to decrease to $14,497 per year. This reduction translates to a considerable payback period of 4.7 years and an IRR of 8.3%.
