“…Compared to other contaminants in groundwater, nitrate plays a vital role in groundwater quality aided with human health issues. The excess concentration of nitrate and continuous consumption of nitrate in groundwater causes serious health diseases on infant and different ages of peoples (Alardhi et al 2020a, Albayati and Doyle 2013Albayati et al 2020).…”

The specific objective of the present is to evaluate the human health issue due to the continuous consumption of nitrate-contaminated groundwater among the various age groups of people. In the study, 40 groundwater samples were collected during the post-monsoon season, and the major ions were analysed in a laboratory. Chadha plot revealed that weathering of parent rocks, ion exchange process and leaching of salts from the rocks are primary sources of groundwater contamination. Nitrate concentration varied from 24 to 78 mg/L with a mean of 46.45 mg/L. Nitrogen pollution index (NPI) value divulged that 40% and 17.5% of sample locations are moderately and significantly polluted due to elevated nitrate concentration in groundwater. The human health risk assessment model revealed that health issues are among the various age groups which are infants > kids > children > aged peoples > adults. The nitrate’s identified sources are leaching of salts from the rocks, using synthetic fertilizers, uncovered septic tanks and improper disposal of household waste from the residential area. Therefore, periodic inspection of water supply, health check-up and inspection of underground pipelines are the remedial measures that should be taken to reduce the severe effects of nitrate-contaminated drinking water in the study area.

“…The existence of a powerful H-bonding with surface hydroxyl group (OH) interactions between them resulted in a broad band around 3400 cm −1 . Eventually, the OH bonds deformation modes of adsorbed H 2 O can be attributed to the band at roughly 1631 cm −1 [ 40 , 41 ]. Due to its low metal content, the loaded metal possessed a spectrum that is quite similar to SBA-15.…”

“…Adsorption is considered the utmost extensive and conventional purification method for the removal of organic, inorganic, and biological pollutants, which are soluble and insoluble in water [ 20 , 21 , 22 , 23 , 24 , 25 ]. Adsorption is an environmentally friendly, cost-effective, and economic method and can substitute the traditional PW treatment methods [ 26 , 27 ]. Moreover, the adsorption process has a wide range of applications and attractive removal efficiency with a simple design and operation.…”

Clay-Alginate Beads Loaded with Ionic Liquids: Potential Adsorbents for the Efficient Extraction of Oil from Produced Water

Produced water (PW) generated from the petroleum industry, during the extraction of oil and gas, has harmful impacts on human health and aquatic life, due to its complex nature. Therefore, it is necessary to treat it before discharging it into the environment in order to avoid serious environmental concerns. In this research, oil adsorption from PW was investigated using clay-alginate beads loaded with ionic liquids (ILs), as the adsorbent material. The effects of several process parameters, such as the initial concentration of oil, contact time, pH, and temperature on the removal efficiency of the beads, were analyzed and optimized. Different characterization methods, such as the Fourier transform infrared spectrophotometer (FTIR), scanning electron microscopy (SEM), energy dispersive X-ray (EDX), and thermal gravimetric analysis (TGA), were used to investigate the surface morphology, the chemical bond structure and functional group, and the thermal stability of the ILs-based beads. The results revealed that the clay-alginate-ILs beads indicated a removal efficiency of 71.8% at the optimum conditions (600 ppm initial oil concentration, 70 min contact time, 10 pH, and at room temperature) with an adsorption capacity of 431 mg/g. The FTIR analysis confirmed the successful chemical bond interaction of the oil with the beads. The SEM analysis verified that the beads have a porous and rough surface, which is appropriate for the adsorption of oil onto the bead’s surface. The TGA analysis provides the thermal degradation profile for the clay-alginate-ILs. The beads used in the adsorption process were regenerated and used for up to four cycles.
