Comment on "Magnetic tubular nickel@silica-graphene nanocomposites with high preconcentration capacity for organothiophosphate pesticide removal in environmental water: Fabrication, magnetic solid-phase extraction, and trace detection" [J. Hazard. Mater. 457 (2023) 131788].

The field of adsorption is seen with mistrustfulness by Scientific Society. One of these reasons is that many users of adsorption do not have knowledge of several concepts of physical chemistry, and they spread misconceptions throughout the literature. One point that is usually found to be wrong in papers published even in prestigious Journals involving adsorption is the thermodynamics of adsorption, the use of linearization for modeling the equilibrium and kinetics of adsorption, and other misconceptions related to adsorption.

Removal of inorganic toxic contaminants from wastewater using sustainable biomass: A review.

Lignocellulosic biomass is most abundant, ecofriendly and sustainable material on this green planet which has received great attention due to exhaustion of petroleum reserves and various environmental complications. Due to its abundance and sustainability, it has been opted in number of advanced applications i.e.

Cellulose-g-poly-(acrylamide-co-acrylic acid) polymeric bioadsorbent for the removal of toxic inorganic pollutants from wastewaters.

Cellulose biopolymer was functionalized by free graft copolymerization and used as a new adsorbent to eliminate toxic inorganic pollutants from wastewater. Functional graft copolymers from cellulose were characterized by FT-IR spectroscopy, XRD, TGA, and SEM-EDX techniques.Cellulose-g-poly-(acrylamide-co-acrylic acid) polymer adsorbent showed high adsorption capacities for the Cd, Cu, Pb and Zn toxic metal ions, which were evidenced by the comparison with unmodified cellulose-richsamples.

Chemical modification of cellulosic biopolymer and its use in removal of heavy metal ions from wastewater.

Use of biological macromolecules for wastewater remediation process has become the topic of intense research mostly driven by growing concerns about the depletion of petroleum oil reserves and environmental problems. So in view of technological significance of cellulosic biopolymers in various fields, the present study is an attempt to synthesize cellulosic biopolymers based graft copolymers using free radical polymerization. The resulting cellulosic polymers were characterized by Fourier transform infrared spectroscopy (FT-IR), Scanning electron microscopy (SEM), X-ray diffraction (XRD) and thermogravimetric (TGA) analysis.
