“…An adsorbent dosage of 0.011 g with a contact duration of 68 min resulted in a maximum removal rate of 93% and a maximum adsorption capacity of 115.8 mg g −1 . Additionally, the adsorbent's reusability of roughly 7 times demonstrated its successful removal of nickel [104].…”

Carbon nanotubes (CNTs), a type of carbonaceous material, have extremely distinctive qualities in terms of tensile strength, heat stability, electrical conductivity, catalysis, and adsorption. These properties rely on structure, length, and thickness. Carbon nanotube and metal oxide combination have been successfully used over the past few decades to create carbon nanomaterials with extraordinary features. The current study offers an outline of the developments in the theory, procedures, and chemical modification of CNT with metals or polymers. This review presents different synthesis methods of functionalized CNTs along with their properties and factors affecting their adsorption capacity. In addition, it explains the role of different functionalized CNTs in removing different metals like Pb2+, Cd2+, Cr3+, Cr6+, Ni2+, Tl+3, and Hg2+ from wastewater. The adsorption capacity of these modified CNTs is in the range of 130-180 mg/g. This review offers an essential understanding of the methods for creating multifunctional nano-hybrids for a variety of applications and future prospects of the use of nanomaterials for environmental remediation.

“…Similar to Pb(II), nickel is an essential element for living organisms in small quantities; however, it becomes toxic and hazardous at high concentrations through bioaccumulation. 188 Thus, nickel content at levels that are higher than the permissible levels in water resources must be eliminated, if not reduced to allowable limits. 189 To date, different methods have been used for the removal of Ni metal ions from water supplies, such as ion exchange, chemical deposition, membrane separators, microbial precipitation, biosorption, and adsorption.…”

Sustainable technologies applied to energy-related applications should develop a pivotal role over the next decades. Therefore, the development of new materials for old processes has merged as a central research line lately. Deep eutectic solvents (DESs) have been recently considered alternative and economic task-specific solvents for many chemical and environmental processes. The low-cost production of DESs production from natural sources and their tunable properties, such as neat null toxicity and biodegradability, make these solvents suitable candidates for various processes within the green chemistry framework. Considering the millions of possible DES combinations yet to be explored, a detailed review of DES research’s current status that can elaborate on the structure–property relationship is an essential task to identify the missing links and strong points on DES research. Thus, this review work focuses on the recent research efforts on the utilization of DES on chemical processes, with the purpose of elucidation on gas capture/separation, fuel desulfurization, biodiesel production, and water treatment processes and provides a deeper understanding on outstanding scientific questions and identifies promising new research directions that involve DESs.

“…As well, model compatibility and statistical significance were considered using the regained values for correlation coefficients (R 2 ). The proposed model can be considered to be statistically appropriate at 95% confidence level due to the p-value less than 0.0001 in the ANOVA table (Rahmati;.…”

Antibiotics along with their metabolites due to their toxicity and low biodegradability have adverse effects to human and animal health. This work can help to monitor and elimination of the residue of the cloxacillin (Clox) antibiotics in two ways: the first part involves design and fabrication of a new electrochemical nanosensor based on a screen-printed carbon electrode modified with gold nanourchin and graphene oxide for detection and determination of Clox in aqueous media. The second part focuses on the preparation of carbon nanocomposites modified with multi-walled carbon nanotubes (MWCNT/CC) as adsorbent for the removal of Clox from aqueous medium. The MWCNT/CC nanocomposites were made using sol-gel process and then the efficiency of the antibiotic removal was assessed by the designed nanosensor. In Clox removal experiments, the effect of independent variables including pH, exposure time, extent of MWCNTs and amount of adsorbent on the removal of antibiotic as a dependent variable was investigated using response surface methodology. The morphological and physical properties of the suggested adsorbent were explored. The maximum efficiency of Clox removal (97%) was achieved in conditions of using 1.52 g/L of the adsorbent fabricated by 2.9 wt. % of MWCNTs in 0.1 M phosphate buffer solution at pH of 5.0 during 75 minutes. The highest adsorption capacity of the MWCNT/CC was 296 mg/g at optimal conditions.
