Abstract Amidst the increasing problems of water scarcity and textile pollution, wastewater treatment industry is in dire need affordable adsorbents. The needs to find cost-effective ways mitigate its environmental impact, as it a major cause pollution. Since stress globally, adsorbents are crucial for providing sustainable approachable solutions pollution problems, guaranteeing efficient treatment, encouraging preservation face growing concerns. purpose this study determine how well waste basalt quarry dust (BQD) works an adsorbent remove malachite green (MG) dye, cationic dye that source characterization BQD reveals zeta potential -23.3 mV, which promising indication MG adsorption. According BET analysis, surface area 8.731 m2/g, pore volume 0.015 cc/g, width 3.794 nm. Various kinetic equilibrium models used investigate adsorption process. kinetics show well-fitted pseudo-first-order non-linear model with adjusted R2 value 0.99415. This shows effective reliable adsorbent. Sips isotherm excellent fit 0.9827, demonstrating robustness Thermodynamic studies emphasize spontaneity exothermic nature In addition these, response methodology optimising removal efficiency, quadratic central composite design process, exhibiting predicted 0.9917, greater than artificial neural network (R2 = 0.9698). Desorption also demonstrate remarkable resilience adsorbent, maintaining 85% effectiveness after five cycles using 0.5 M HCl eluent. highlights long-term reuse BQD, supporting circular economy by advancing development processes environmentally friendly, utilizing byproducts from one resources treat another.

Abstract Silver-zinc-nickel spinel ferrite was prepared by the co-precipitation procedure with precise composition Ag 0.1 Zn 0.4 Ni 0.5 Fe 2 O 4 for bolstering pollutant removal effectiveness while upholding magnetic properties and then coated a mesoporous silica layer. The surface characteristics of @mSiO were confirmed using EDX, FT-IR, VSM, XRD, TEM, SEM, BET methods. modification Ag-Zn-Ni layer improves texture properties, where specific area average pore size rose to 180 m /g 3.15 nm, respectively. ferrite@mSiO has been utilized as an efficient adsorbent eliminating methyl green (MG) indigo carmine (IC) models cationic anionic dyes from wastewater, Studying pH, Pzc, dosage, dye concentration, temperature showed that MG carried out in alkaline media (pH = 12), acid medium 2) effective IC removal. Langmuir isotherm pseudo-second-order kinetics found be good fits adsorption data. Both adsorbed spontaneous, endothermic process. A possible mechanism proposed. effectively recovered reused.

In the current research Russula delica mushroom/bentonite clay (RDBNC) as a low-cost bionanosorbent was investigated for adsorption of methylene blue (MB) and malachite green (MG) dye from contaminated water. The characterized by Fourier transform infrared (FTIR), X-ray diffraction (XRD), Scanning electron microscopy (FESEM), Thermal Gravimetric Analysis (TGA), Zeta-potential techniques. Adsorption experiments RDBNC MB, MG dyes following Freundlich isotherm pseudo second order kinetic models. To determine their effects on efficiency, parameters were including concentration, contact time, temperature, dosage bionanosorbent. process can operate through three primary mechanisms: π-π interaction, hydrogen bonding, electrostatic interactions between surface dyes. Desorption results revealed that MB effectively desorbed during fourth cycle without notable loss in capacity. thermodynamics ΔH, ΔS, ΔG, determined, favorable, spontaneous, exothermic MG. showed RDBNC, which effective inhibition at low concentrations, especially against E. coli, be used synthesised first time to remove industrial

In this study, artificial neural network (ANN) tools were employed to forecast the adsorption capacity of Malachite green (MG) by baru fruit endocarp waste (B@FE) under diverse conditions, including pH, adsorbent dosage, initial dye concentration, contact time, and temperature. Enhanced efficiency was notably observed alkaline pH conditions (pH 10). Kinetic analysis indicated that process closely followed a pseudo-second-order model, while equilibrium studies revealed Langmuir isotherm as most suitable estimating maximum 57.85 mg g

Abstract Selective adsorption plays an important role in the resource utilization of dye wastewater. Hydrated calcium silicate (CSH), as ideal material, is successfully compounded on surface polypropylene (PP) fibric by quasi‐solid‐phase method, and porous film formed PP fabric. The contact angle fibers changed from 130.7° to 62.4° due hydrophilic characteristics CSH polyvinyl alcohol. for dyes shows obvious selectivity, removal ratio methylene blue can reach more than 90%, while there almost no methyl orange. selectivity be attributed electrostatic interaction between dyes. contains anion chains, resulting a large number negatively charged sites distributed surface, which may main reason cationic through interactions. investigation kinetics that formation coordination bonds will also lead further enhancement capacity.
