Most of the current techniques used to mitigate the toxic effects of heavy metals have limitations. This creates an urgent need to explore safer and more efficient methods to address these toxic effects. This study investigates the potential of nano-water hyacinth protein (nano-WHP) as an adsorbent and soil amendment to mitigate cadmium pollution. Nano-WHP is derived from water hyacinth protein and immobilized on nano-chitosan. The Cd adsorption capacity and removal efficiency of nano-WHP were determined. Nano-WHP was applied as a soil amendment to examine its impact on soil enzyme activity and the growth of common bean plants under Cd stress. Nano-WHP could remove 96% of Cd with an adsorption capacity of 150 mg Cd g⁻1. When used as a soil amendment under Cd stress, nano-WHP positively influenced soil enzyme activity, enhancing soil health and promoting the growth of common bean plants. The growth of nano-WHP-treated plants increased by approximately 35% and 50% in the first and second stages, respectively, compared to the control group under cadmium stress. Furthermore, nano-WHP significantly reduced oxidative stress markers such as lipid peroxidation, DNA oxidation, protein oxidation, and H₂O₂ levels, with reductions of about 90.63%, 85.13%, 79.35%, and 81.85%, respectively, compared to untreated plants. This reduction in oxidative stress markers is attributed to the lower availability of Cd and the heightened activity of the antioxidant machinery in nano-WHP-treated plants. These results establish a foundation for the formulation of sustainable and economically feasible methodologies to mitigate Cd contamination.","PeriodicalId":458,"journal":{"name":"Adsorption","volume":"48 1","pages":""},"PeriodicalIF":2.318,"publicationDate":"2024-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141573881","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Langmuir model, which does not take into account sorbate-sorbate bonds, is the most common one for interpreting monolayer adsorption.When using it, the assumption about the absence of sorbate-sorbate interactions between the sorbate molecules of the first layer is never checked. However, the sorbate-sorbate interactions can make an important contribution to the adsorption energy at physical adsorption. In this case, the formation of sorbate clusters in first layer is an energetically preferable process compared to the process of individual molecules adsorption. The monolayer cluster adsorption model, which takes into account sorbate-sorbate interactions, was introduced in our previous works. In present work, based on the experimental isotherms analysis, a criterion for the mechanism of monolayer adsorption (cluster or adsorption of individual molecules) is proposed. Examples are given of the this criterion application to the study of the mechanism of carbon dioxide adsorption by IRMOF-6, IRMOF-11 and IRMOF-1, ethane by highly activated carbon Saran and methane by mica.

In this study, adsorption and desorption of hydroxychloroquine on sulfur (S)-doped graphene powders were investigated. While the adsorption experiments were carried out in the environment of distilled water (pH 5.0-6.0), HEPES buffer (pH 7.6), and Tris.HCl buffer (pH 8.0) the desorption studies were performed in distilled water. The HCQ adsorbed S-doped graphene powders were characterized by UV-Vis, FT-IR, XRD, BET and TEM techniques. According to UV-Vis measurements, the adsorption efficiency in the HEPES buffer medium at pH 7.6 was the highest (68.72% for H3 (HCQ adsorption with SGr3 graphene in HEPES medium)). FT-IR and XRD analyses confirmed the presence of HCQ on the graphene powders’ surface. While morphological changes on the surfaces of graphene powders were imaged by TEM, BET surface area changes proved the HCQ adsorption. The in vitro toxicity of the developed H3 was found to be lower than that of HCQ alone on the L929 cell line. These fundamental findings of the surface interaction between HCQ and graphene are precious for the design and optimization of a targeted drug based on this molecule and material.

Physicochemical parameters of the sample show, a strong and moderate correlation between all parameters while a weak correlation of turbidity. The synthesized materials were also characterized using powder XRD, FT-IR, UV-VIS spectroscopy, SEM, and conductometer. The physical characterization shows the amorphous nature of MO and the crystallinity of polyaniline and composite material. The existence of skeletal interaction, electronic transition, and porous and granular morphology was confirmed using FT-IR, UV-VIS spectroscopy, and SEM, respectively. After physical characterization, the adsorption performance of as-synthesized material was tested using the batch method. The maximum adsorption capacity (qmax) of Cu2+ and Pb2+ ions by PANI/MO was 10.01 mg/g and 23.01 mg/g, respectively. When all parameters were optimized (pH at 5, contact time at 30 min, temperature at 250C, and 2 grams of PANI/MO) adsorption efficiency for Pb2+ is 99%, and Cu2+ ions is 97.77%. The Freundlich isotherm data for Cu2+ and Pb2+ have a good fit with the experimental data (R2 = 0.99 and 0.98), and Langmuir isotherm data for Cu2+ and Pb2+ is RL=0.18 & 0.19, respectively. The pseudo-second-order kinetic isothermal was more fit with physisorption at R2 = 0.99 for Cu2+ and R2 = 1 for Pb2+.

In this study, progressing in the field of Catalytic Nanomedicine, we investigated the cytotoxic effects of a novel class of bionanocatalysts on glioma cancer cells. These bionanocatalysts were constructed from a catalytic matrix of oxides with evenly dispersed superficial copper-coating nanoparticles. This design optimizes both the inherent catalytic characteristics of the matrix and instills cytotoxic properties. The bionanocatalysts coated with copper demonstrated a significant reduction in cancer cell viability when compared to reference bionanocatalysts without the transition metal. We also observed structural damage to the cytoskeleton and alterations in mitochondrial activity. These findings suggest that these pathways are integral to the mechanisms through which these nanostructures execute their bionanocatalytic activities, particularly in breaking chemical bonds. Importantly, our physicochemical analyses verified that the coating with copper species, primarily CuO, did not disrupt the individual structure of the bionanocatalysts: instead, it enhanced their catalytic cytotoxic potential. This research aims to deepen our understanding of the mechanisms underlying this promising antineoplastic treatment and underscore the effectiveness of superficial copper-coating nanoparticles as agents for amplifying the inherent properties of bionanocatalysts through nanocatalysis.","PeriodicalId":458,"journal":{"name":"Adsorption","volume":"32 1","pages":""},"PeriodicalIF":2.318,"publicationDate":"2024-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141529584","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
