This study provides a solution for the treatment of heavy metal ions as well as common organic pollutants in water by adsorption, which contributes to the achievement of sustainable development goals. In this work, a new adsorption material, β‐cyclodextrin‐acrylic acid‐acrylamide (CD‐AA‐AM‐MBA), is synthesized. The structure of the materials is characterized and analyzed using fourier transform infrared spectroscopy (FT‐IR), Xray diffraction spectroscopy(XRD), scanning electron microscopy(SEM) and thermogravimetric analysis(TGA). The effects of initial ion concentration, contact time, and different pH values on the adsorption performance are studied. Under the optimized conditions, the adsorption capacity in CD‐AA‐AM‐MBA of Cu2+, Pb2+, Cd2+, Methylene Blue(MB), Methyl Orange(MO), phenol, m‐cresol and p‐cresol are 58.66, 326, 48.5, 58.27, 51.34, 6.63, 3.7 and 5.91 mg g−1.

“…Adsorbent characteristics are affected by the both pH of the working solution and the abundance of metal ions in the solution (Negi et al, 2023). The scope of removing Cd (II) ions was analyzed by altering the pH of the working solution from 2-7, by keeping the other parameters constant (45 min of contact time, 1 g of biosorbent dose, initial metal ion concentration of 10 mg/L at 298±1.5 K temperature and 170 rpm stirring speed.…”

Heavy metal contaminants are naturally carcinogenic, poisonous, and persistent. In the elimination of harmful heavy metals from polluted water, developing a novel revolutionary biosorbent with high efficiency and low cost from native biomaterial is a difficult task. The utilization of Tectona grandis (teak) leaves to make a possible biosorbent (TGLB) for extracting Cd (II) ions from contaminated wastewater solutions was investigated. To validate the sorption capacity of TGLB, the characteristics of the biosorbent were studied using Scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), point of zero charge (pHPZC), and Brunauer-Emmett-Teller (BET) textural analysis. pH, time, biosorbent dose, temperature, and metal ion concentration were all altered in the batch studies. 93.2% maximal elimination at ideal pH 5 was achieved for a 5 g biosorbent dose, a working solution with a purity of 10 mg/L after a 45 min contact duration. In order to validate the research, the experimental data were also subjected to single-factor analysis (One-way ANOVA) and t-test. The Langmuir sorption model (R2 > 0.999) and pseudo-second-order kinetic model (R2 > 0.998) were the best matches for experimental sorption outcomes. The desorption studies implied that TGLB can be utilized efficiently for three consecutive cycles. A study of the utmost adsorption capabilities of numerous untreated biomaterial-based residues revealed that Tectona grandis leaves biosorbent (TGLB) is an effective, cheap, ecologically and economically friendly biosorbent for application in the elimination of the heavy metals from contaminated aqueous solutions.

A three-dimensional porous bacterial cellulose/graphene oxide (BC/GO) composite hydrogel (BC/GO) was synthesized with multi-layer graphene oxide (GO) as the modifier and bacterial cellulose as the skeleton via an ultrasonic shaking process to absorb lead ions effectively. The characteristics of BC/GO were investigated through TEM, SEM, FT-IR, NMR and Zeta potential experiments. Compared to bacterial cellulose, the ultrasonic method and the carboxyl groups stemming from GO helped to enhance the availability of O(3)H of BC, in addition to the looser three-dimensional structure and enriched oxygen-containing groups, leading to a significantly higher adsorption capacity for Pb(II). In this paper, the adsorption behavior of BC/GO is influenced by the GO concentration, adsorption time, and initial concentration. The highest adsorption capacity for Pb(II) on BC/GO found in this study was 224.5 mg/g. The findings implied that the pseudo-second-order model explained the BC/GO adsorption dynamics and that the data of its adsorption isotherm fit the Freundlich model. Because of the looser three-dimensional structure, the complexation of carboxyl groups, and the enhanced availability of O(3)H, bacterial cellulose exhibited a much better adsorption capacity.
