“…The average size of the nanoparticles was 82.13 nm, which is close to that obtained from the XRD. This result is similar to that reported for the synthesis of CuONPs using the aqueous leaf extract of Phyllanthus emblica 29 . Moreover, the CuONPs had a somewhat porous structure with a slight agglomerated morphology.…”

Copper oxide nanoparticles (CuONPs) have received tremendous attention as efficient adsorbents owing to their low cost, desirable surface area, abundant active sites, potent textural characteristics and high adsorption capacities. However, CuONPs have not been employed to decontaminate water laden with increasing environmental contaminants such as thiazolyl blue and paracetamol. Herein, the adsorption of thiazolyl blue and paracetamol onto green synthesized CuONPs prepared from the aqueous leaf extract of Platanus occidentalis was studied. The BET, SEM, FTIR, XRD, EDX and pH point of zero charge showed the successful synthesis of CuONPs having desirable surface properties with a surface area of 58.76 m2/g and an average size of 82.13 nm. The maximum monolayer adsorption capacities of 72.46 mg/g and 64.52 mg/g were obtained for thiazolyl blue and paracetamol, respectively. The Freundlich, pseudo-second-order and intraparticle diffusion models were well fitted to the adsorption of both pollutants. The pH studies suggested the predominance of electrostatic and weaker intermolecular interactions in the adsorption of the thiazolyl blue and paracetamol, respectively. Spontaneous, physical, endothermic and random adsorption of the pollutants on CuONPs was obtained from the thermodynamic consideration. The biosynthesized CuONPs were found to be highly reusable and efficient for the adsorption of thiazolyl blue and paracetamol from water.

“…In the recent years, the reports of As contamination exceeding the environmental and wastewater standards in industrial wastewater have been increasing worldwide [ 1 , 2 , 3 , 4 , 5 , 6 ]. According to the latest fact sheets from WHO [ 7 ], tens of millions of people have consumed high-concentration As-contaminated groundwater [ 8 , 9 ]; health problems such as skin cancer caused by the As contaminants have become a major social problem [ 2 , 10 , 11 ]. Therefore, the development of advanced materials or technologies for the efficient treatment of As wastewater continues to be a global research priority.…”

A cationic polymer gel (N-[3-(dimethylamino)propyl]acrylamide, methyl chloride quaternary)(DMAPAA-Q gel)-supported oxidising agent (KMnO4 or K2Cr2O7) was proposed to remove As from water. The gel could adsorb arsenite, As(III), and arsenate, As(V), through the ion exchange method, where the oxidising agent oxidised As(III) to As(V). theoretically speaking, the amount of oxidant in the gels can reach 73.7 Mol%. The maximal adsorption capacity of the D-Mn gel (DMAPAA-Q gel carrying MnO4−) and D-Cr gel (DMAPAA-Q gel carrying Cr2O72−) for As(III) could reach 200 mg g−1 and 263 mg g−1, respectively; moreover, the As(III) removal rate of the gels could still be maintained above 85% in a neutral or weak acid aquatic solution. Studies on the kinetic and adsorption isotherms indicated that the As adsorption by the D-Mn and D-Cr gels was dominated by chemisorption. The thermodynamic parameters of adsorption confirmed that the adsorption was an endothermic process. The removal of As is influenced by the co-existing high-valence anions. Based on these results, the gels were found to be efficient for the As(III) adsorption and could be employed for the As(III) removal from the industrial wastewater.

“…The manufacture of a simple copper oxide nanoparticle (CuO NPs) utilizing Phyllanthus emblica leaf extract as fuel has been proven, as P. emblica is a locally plentiful plant. CuO NPs were produced and employed as an absorbent to extract As(V) from water [62]. Mike O et al [63] achieved bifunctional magnetic nanoparticles by covalently coupling an imine ligand, 4-[(E)-phenyl methylidene] amino benzoic acid (Maph-COOH), with amine modified magnetic nanoparticles (MNP-NH2) in batch adsorption experiments for the uptake of Zn (II) and As (III) from aqueous solutions.…”

Millions of people worldwide are adversely affected by Arsenic continuing exposure, so providing arsenic-free consumption of water is an immense task for the researchers. The chemistry, content of arsenic-contaminated water as well as adsorption play a big role in arsenic elimination. The mechanism of adsorption technology's elimination of As (V) from the water was simply presented as the elements that govern various adsorption paths. The effects of a variety of adsorbents on As (V) elimination from aquatic were explored in the present research, which classified the materials used as adsorbents based on physical, chemical, and biological processes. When choosing an adsorbent, adsorption capability is an important factor to consider. As a result, developing As (V) elimination from aquatic adsorption strategies includes developing environmentally acceptable materials with effectual adsorption abilities, refining the preparation and alteration procedures of recent adsorbents, and boosting renewal effectiveness. After choosing a particular adsorbent for As (V) elimination from water, regional features of arsenic-polluted water, applied viability of the adsorption process, besides suitable environments of respectively material must be extensively reviewed and analyzed. The current study gives an outline of the adsorption technique to remove arsenic from wastewater, as well as the adsorption capacity of various adsorbents.
