“…Antimony (Sb) is potentially toxic to humans, so it needs to get controlled to prevent its severe effects on humans. 98 Antimony compounds possess the ability to introduce diseases like Hypoxia (absence of enough oxygen in the tissues to sustain bodily functions) and other metabolic disorders because the compounds of Antimony abstract the enzyme activities. Antimony exists in two states Sb(III) and Sb(V).…”

Bimetallic nanoparticles have attracted huge attention because they exhibit more efficient characteristics due to the extensive array of chemical and physical properties, synergistic effects, and different mechanisms of action. This review highlights the synthetic routes for synthesis of different bimetallic nanoparticles such as physical, chemical, and biological routes and their use for the removal of pollutants from water such as heavy metals, metalloids, dyes, pharmaceuticals, bacteria’s etc. The study shows that bimetallic nanoparticles have been synthesized by various methods and used for the purification and application of water. It also is revealed that the bimetallic nanoparticles are efficient for removal of organic, inorganic, and biological pollutants from water. Furthermore, an up to date review of use of various bimetallic nanoparticles for water treatment is presented in the form of table and the future perspectives and challenges in the field are discussed in detail.

“…The initial pH of the treated solution significantly influences the entire adsorption process as it relates to changes in charges on the surface of the adsorbent and the protonation/deprotonation of adsorption sites (Liu et al 2021). The pH also affects the behavior of metal ions in the aqueous medium (Cruz-Lopes et al 2021), making the adsorption process efficiency and adsorbent performance dependent on the solution pH.…”

The incorporation of cellulose nanowhiskers (CNWs) in superabsorbent hydrogels of starch grafted with poly(acrylic acid) (ST-g-PAAc) is proposed as a strategy to obtain adsorbent materials with superior performance for Pb(II) removal. The functionalized surface of CNWs provides additional interaction sites, contributing to the high adsorption capacity (935.8 mg/g) of the composite hydrogel. The presence of CNWs also minimizes the effects of temperature and competition with other ions, making the adsorption process more stable and efficient. Density functional theory (DFT) calculations revealed that the hydroxyl groups of CNWs play a crucial role in providing additional binding energies (approximately 30 kcal/mol) for the Pb(II) ions, favoring the spontaneity and kinetics of the adsorption process. The adsorption process on the CNWs-containing hydrogel involves chemisorption and intra-particle diffusion, indicating multiple steps occurring during the adsorption of Pb(II) ions. Also, the CNWs-containing hydrogel demonstrates excellent reusability, showing minimal loss of adsorption capacity after consecutive reuses. This characteristic makes the composite highly attractive for practical applications in real-world scenarios. In short, the systematic evaluation of different experimental conditions has confirmed the superior adsorption performance of the composite hydrogel and gives light on the role of CNWs as a valuable nanofiller to enhance the adsorption properties of these materials.
