Magnetic carrageenan gum-grafted-polyacrylamide nanocomposite for uptake of cationic dyes from the aquatic systems.

Using an ex-situ growth approach, this research fabricated k Carrageenan/Polyacrylamide@magnetite nanocomposites (NCs), (k-Car/PAM@Magnetite NCs). The k-Carrageenan (k-Car) backbone was modified through graft polymerization of acrylamide (PAm) via radical polymerization using ammonium persulfate (APS) as the initiator. N'-N' methylenebisacrylamide (MBAA) was used as the cross-linking agent, and magnetic nanoparticles (MNPs) were incorporated to impart magnetic properties.

Removal of organic contamination from wastewater using granular activated carbon modified-Polyethylene glycol: Characterization, kinetics and isotherm study.

To effectively remove Diazinon (DZ), Amoxicillin (AMX), and Crystal Violet (CV) from aquatic environments, a novel granular activated carbon (GAC) modified with Polyethylene glycol 600 (PEG) was created and manufactured. The chemical properties were investigated using a variety of characteristic analyses, including FT-IR, XRD, FESEM, and N2 adsorption/desorption. The effectiveness of GAC-PEG's adsorption for the removal of DZ, AMX, and CV was assessed under a variety of conditions, including a pH of 4-9 for the solution, 0.

Remediation of Safranin-O and acid fuchsin by using TiC MXene /rGo-CuO nanocomposite: Preparation, characterization, isotherm, kinetic and thermodynamic studies.

In recent years, MXene has become one of the most intriguing two-dimensional layered (2Dl) materials extensively explored for various applications. In this study, a TiC MXene/rGo-CuO Nanocomposite (TGCNCs) was developed to eliminate Safranin-O effectively (SO) and Acid Fuchsin (AF) as cationic dyes from the aquatic environment. Multistep was involved in the preparation of the adsorbent system, including the Preparation of TiC, after that, GO synthesis by the Humer method, followed by rGO production, then added CuSO to obtain a final Nanocomposite (NCs) called "TGCNCs".

Functionalization of chitosan by metformin, nickel metal ions and magnetic nanoparticles as a nanobiocomposite for purification of alkaline phosphatase from hen's egg yolk.

In this study, a novel and green chitosan-metformin/NiCl/FeO nanobiocomposite was synthesized and used to purify alkaline phosphatase (ALPs) from hen's egg yolk. For this purpose, after functionalization of the chitosan biopolymer by terephthaloyl chloride-metformin ligand, the coordination with Ni(II) and magnetization process were performed. The structure and properties of the synthesized nanobiocomposite were then evaluated by using analyzes such as FT-IR, EDX, FE-SEM, XRD, TGA and VSM.
