In this work, a germanium ion-imprinted polymer (Ge-IIP) based on α-bromobutyric intercalation-modified hydrotalcite was synthesized by atom transfer radical polymerization and applied for the capture of ions from wastewater. particular, layered as skeleton support induced in situ Ge-IIPs to form graded pores, an interlayer also used initiator induce graft functional monomers 3-dihydroxypropyl-2-acrylate strong coordination cavities ions. Batch experiment results showed that could effectively at pH value 3, maximum adsorption capacity up 55.18 mg·g–1. The kinetics isotherms indicated consistent with pseudo-second-order kinetic model Freundlich isotherm model. distribution coefficient values Ge(IV) coexisting metal ion solution were high 25 231.36 mL·g–1, indicating significant selectivity. addition, good reusability, uptake rate still reach 98.45% after 5 cycles. Furthermore, density theory calculation efficient selective may be attributed exchange surface complexation between abundance o-hydroxyl groups Ge-IIP structure. excellent salt tolerance selectivity provide possibility its practical application recovery

Опубликована: Апрель 18, 2024

Though nowadays germanium do not reach the range of popularity than other metals, i.e. rare earth elements, its utility in target industries makes it also a strategic metal. can be find series raw materials, principal source for recovery is from secondary wastes zinc industry, and also, recycle germanium-bearing waste materials becoming interest. In this recovery, Hydrometallurgy performing key role to successful achievement goal. The present work reviews most recent applications (2023 2024 years) hydrometallurgical operations on different solid liquid sources.

The compound triclosan (TCS) is widely found in personal hygiene products, and when present effluents, it can cause problems to human health, such as endocrine disruption, intestinal problems, liver tumors. A sustainable alternative for the removal of TCS use adsorbent biopolymers, which are low-cost, renewable, biodegradable. One most used biopolymers chitosan (CHT), has excellent adsorptive properties due its functional groups. In this context, work evaluated, through computational simulations, interaction molecule with CHT. frontier molecular orbitals electrostatic potential show that different forms interactions occur, thus, five complexes were shown be stable after optimization interactions. bond lengths ranged from 1.839 Å 3.606 formed mainly by hydrogen bonds H...Cl binding energy (∆EBind) allowed us infer adsorption occurred, ∆EBind < 0, values -4.14 kcal mol-1 -17.74 mol-1. thermodynamic demonstrated process was exothermic two spontaneous: TCS...CHTiii ΔG= -3.14 TCS...CHTiv -2.82 topological parameters revealed almost all between CHT electrostatic, non-covalent analysis confirmed presence van der Waals complexes. Thus, study showed efficient treatment effluents containing emerging contaminant triclosan.
