“…They can cause serious health effects, lead to death, renal and hepatic disease, neurological problem, liver damage, and so forth, in the human body through the food chain . The plants also get affected in seeds germination, cellular components, rate of growth by affecting the metabolism, and so forth, by the presence of toxic metal ions in the soil . The permissible limit of copper ions in inland surface water set‐up by IS, EPA, and WHO are 0.25, 3.0, and 2.0 mg.L −1 , respectively .…”

The study presents the removal of Cu(II) ions using bio‐adsorbents. The applicability of the continuous column process using hyacinth root, rice husk, blackberry leaves, and guava leaves is reported in this study. The effects of solution pH were studied in batch mode, and other different process parameters such as bed depth, rate of flow, influent solution concentration were investigated and optimized in the continuous mode. The breakthrough curves were obtained for various initial metal concentrations (10, 20, and 30 mg.L−1), flow rates (10, 30, and 40 ml.min−1), and bed height (4, 6, and 10 cm). The optimum operating conditions were 10 cm bed depth, 10 ml.min−1 flow rate, 10 mg.L−1 influent concentration, and pH 6. The breakthrough time was increased with increasing bed height and decreasing flow rate and influent concentration. The Freundlich isotherm model was in good agreement (R2 = .9247–.9987) with the batch experimental data whereas, the continuous experimental data fitted well in the Thomas model to illustrate the best performance of the fixed‐bed process. FTIR spectra and SEM images verify the sorption capacity of the adsorbents. The Cu(II) adsorption capacities of the adsorbents were compared, and the hyacinth root gives the best result compare to the others. Hence, the results proved the effectiveness of the adsorbents for the removal of Cu(II) ions.

“…The chemical parameters are of utmost importance as these are responsible for determining water quality up to a great extent. The presence of toxic organic contaminants in the water is dangerous for our health as many organics are carcinogenic in nature [ 4 , 5 ]. Phenolic compounds are very toxic to human beings; even at trace levels [ 6 , 7 , 8 , 9 ].…”

Analysis of 4-cyanophenol and 3-nitrophenol was carried out using multi-walled carbon nanotubes-based solid-phase extraction (SPE) and capillary electrophoresis (CE) methods. Capillary electrophoresis was carried out with 18 kV voltage, 214 nm detection, and phosphate buffer (pH 7.0, 15 mM) as background electrolyte at 25 ± 1 °C temperature with 15.05 and 16.5 min migration times of 4-cyanophenol and 3-nitrophenol. The separation and resolution factors were 1.10 and 2.90. The optimized experimental conditions were 40 mg/L concentration, 1.0 g multi-walled carbon nanotubes (MWCNTs) per SPE cartridge, 5.0 mL/min flow rate of water, 0.1 mL flow rate of eluting solvent. The maximum recoveries were 91% and 98% at 0.1 mL/min flow rate of 4-cyanophenol and 3-nitrophenol. These methods were applied successfully for extraction and estimation of 4-cyanophenol and 3-nitrophenol in the municipal wastewater. The reported methods are reproducible, efficient, and practical for the estimation of these phenols in water.

“…Besides microorganisms, green plants are also used to remove hazardous compounds, through a process called phytoremediation. This green technology is based on the interaction between plants and soil microbiota to reduce the concentration or toxic effect of pollutants, considered as a cost-effective and effective and sustainable environmental recovery technology (Jeevanantham et al 2019). Several hazardous compounds can be degraded by phytoremediation, including heavy metals (Pb, Zn, Cd, Cu, Ni, Hg), radioactive elements (U, Cs, Sr), petroleum hydrocarbons, pesticides and herbicides (atrazine, bentazone, chlorinated and nitroaromatic compounds), explosives (TNT, DNT), as well as industrial organic wastes (PCPs, PAHs), metalloids (As, Sb) and inorganic compounds ( Just as pollutants from intense industrial activity accumulate in soil and water, fossil fuels as energy sources have raised atmospheric CO 2 to critical levels.…”

The various industrial sectors, as well as livestock and agricultural activities, are increasing the production of inputs to meet the demand of the worldwide demographic explosion, making a challenge the clean maintenance of water, soil, and air. Therefore, the search for solutions for a pollutant-free environment without compromising economic development has become extremely important. Thereby, biotechnological studies in order to solve environmental issues have been gaining extensive attention through the coupling of technology procedures to biological systems as sustainable solutions to remediate contaminated areas. In this sense, this review covers topics such as the role of Omics era in microbial environmental biotechnology for pollution control as well as the microbial fuel cell use in energy production. Moreover, phytoremediation and the perspective of applying chemical methods are approached as environmentally friendly tools for the pollutant control to improve remediation processes.
