Enhancement of adsorption efficiency of crystal violet and chlorpyrifos onto pectin hydrogel@Fe3O4-bentonite as a versatile nanoadsorbent

Scientific Reports, Journal Year: 2023, Volume and Issue: 13(1)

Published: July 4, 2023

The magnetic mesoporous hydrogel-based nanoadsornet was prepared by adding the ex situ Fe3O4 nanoparticles (MNPs) and bentonite clay into three-dimentional (3D) cross-linked pectin hydrogel substrate for adsorption of organophosphorus chlorpyrifos (CPF) pesticide crystal violet (CV) organic dye. Different analytical methods were utilized to confirm structural features. Based on obtained data, zeta potential nanoadsorbent in deionized water with a pH 7 - 34.1 mV, surface area measured be 68.90 m2/g. novelty owes possessing reactive functional group containing heteroatom, porous structure that aids convenient contaminants molecules diffusion interactions between contaminants, viz., CPF CV. main driving forces Pectin hydrogel@Fe3O4-bentonite adsorbent are electrostatic hydrogen-bond interactions, which resulted great capacity. To determine optimum conditions, effective factors capacity CV CPF, including solution pH, dosage, contact time, initial concentration pollutants, have been experimentally investigated. Thus, i.e., time (20 15 min), 8, dosage (0.005 g), (50 mg/L), T (298 K) CV, respectively, 833.333 mg/g 909.091 mg/g. presented high porosity, enhanced area, numerous sites using inexpensive available materials. Moreover, Freundlich isotherm has described procedure, pseudo-second-order model explained kinetics. novel magnetically isolated reused three successive adsorption-desorption runs without specific reduction efficiency. Therefore, is promising system eliminating pesticides dyes due its remarkable amounts.

Polysaccharide nanocomposites in wastewater treatment: A review

Chemosphere, Journal Year: 2023, Volume and Issue: 347, P. 140578 - 140578

Published: Nov. 6, 2023

In modern times, wastewater treatment is vital due to increased water contamination arising from pollutants such as nutrients, pathogens, heavy metals, and pharmaceutical residues. Polysaccharides (PSAs) are natural, renewable, non-toxic biopolymers used in the field of gas separation, liquid filtration, adsorption processes, pervaporation, proton exchange membranes. Since addition nanoparticles PSAs improves their sustainability strength, nanocomposite has gained significant attention for past decade. This review presents a comprehensive analysis PSA-based nanocomposites efficient treatment, focusing on adsorption, photocatalysis, membrane-based methods. It also discusses potential future applications, challenges, opportunities photocatalysis. Recently, have shown promise adsorbents biological-based systems, effectively removing metals that could hinder microbial activity. Cellulose-mediated successfully removed various wastewater, including dyes, oil, organic solvents, pesticides, Thus, PSA would support biological processes plants. A major concern discharge antibiotic wastes industries, posing environmental health risks. PSA-mediated bio-adsorbents, like clay polymeric hydrogel beads, efficiently remove antibiotics ensuring quality ecosystem balance. The successful use bio-adsorbents depends ongoing research optimize application evaluate impacts. Implementing these eco-friendly large scale holds great significantly reducing pollution, safeguarding ecosystems, protecting human health.
