Graphene oxide (GO) exhibits a strong adsorption capacity for the removal of heavy metal ions from liquids, making it topic increasing interest among researchers. However, significant challenge persists in preparation graphene oxide-based adsorbents that possess both high structural stability and excellent capacity. In this paper, green environmentally friendly ternary composite aerogel based on was successfully synthesized. The enhanced through diethylenetriaminepentaacetic acid modification, while incorporation carboxymethyl cellulose improved liquid. demonstrates robust interactions between its components features multiscale porous structure. Adsorption tests conducted with Pb(II) revealed GO/DTPA/CMC (GDC) favorable study kinetics isotherms indicated process follows quasi-secondary model Freundlich model, suggesting chemical multilayer mechanism, maximum 521.917 mg/g quasi-quadratic kinetic fitting. X-ray photoelectron spectroscopy (XPS) scanning electron microscopy (SEM) analyses, performed before after adsorption, confirmed primarily occurs chelation, complexation, proton exchange, electrostatic active sites such as hydroxyl carboxyl groups. This presents an innovative strategy simultaneously enhancing properties aerogels ensuring solution stability.

Abstract Eco-friendly and renewable composite beads were constructed for efficient adsorptive removal of Cr (VI) ions. Attapulgite (ATP) clay decorated with cetylpyridinium bromide (CPBr) was impregnated into cellulose acetate (CA) beads, which formulated through a simple cost-effective solvent-exchange approach. FTIR, XRD, SEM, Zeta potential, XPS characterization tools verified the successful formation ATP–CPBr@CA beads. The displayed spherical porous shape positively charged surface (26.6 mV) at pH 2. In addition, higher adsorption performance accomplished by ease separation compared to their components. Meanwhile, equilibrium isotherms pointed out that Langmuir model optimal describing process maximal capacity 302 mg/g. Moreover, D–R isotherm physical process, while data obeyed pseudo-second-order kinetic model. Further, results hypothesized mechanism involves via electrostatic interactions, redox reaction, co-precipitation. Interestingly, reserved tolerable characteristics maximum present exceeding 70% after reuse seven successive cycles, proposing its feasible applicability as reusable easy-separable candidate removing heavy metals from aquatic bodies.

The global problem of water scarcity is exacerbated by the continued contamination potable sources. This preliminary study investigates potential a hazardous industrial jarosite waste to adsorb As(V) and Cr(III) from contaminated waters. results showed that this mining effectively adsorbed both Cr(III), demonstrating its as low-cost sustainable solution for remediation along with use also contaminates. adsorption process was optimized, effects various parameters on capacity were investigated. findings suggest toxic residues in porous concrete could provide promising approach removal heavy metals polluted sources, contributing development more environmentally friendly treatment technologies. A maximum 90.6% 96.3% achieved, it verified initially contained about 0.44% As, which later leached during decomposition; again, able re-adsorb Cr(III).
