Prediction of Green Solvent Applicability in Cultural Heritage Using Hansen Solubility Parameters, Cremonesi Method and Integrated Toxicity Index

Sustainability, Journal Year: 2025, Volume and Issue: 17(7), P. 2944 - 2944

Published: March 26, 2025

The transition toward sustainable conservation practices requires a scientifically ground approach to substituting traditional solvent systems with green alternatives. This study aims facilitate the adoption of solvents by restoration professionals systematically evaluating their chemical compatibility and toxicological safety. By integrating Hansen solubility parameters (HSP), Relative Energy Difference (RED), Integrated Toxicity Index (ITI), we identified high potential for replacing Cremonesi mixtures. analysis revealed that ether-based solvents, such as 2,5-dimethyltetrahydrofuran cyclopentyl methyl ether, exhibit affinity mixtures, while esters fatty acid (FAMEs) offer balanced combination low toxicity. However, also underscores significant gaps in safety data (SDS) many innovative highlighting need further evaluation before widespread implementation.

Recycling spent lithium-ion batteries offers a sustainable solution to reduce ecological degradation from mining and mitigate raw material shortages price volatility. This study investigates using electrodialysis with selective bipolar ion-exchange membranes establish circular economy for batteries. An experimental data set of over 1700 ion concentration measurements across five current densities, two compositions, three pH levels supports the techno-economic analysis. Selective (SED) isolates lithium ions battery leachates, yielding 99% Li-pure retentate 68.8% retention, achieving relative ionic fluxes up 2.41 Li+ transition metal cations selectivity 5.64 monovalent cations. Bipolar membrane (BMED) converts LiCl into high-purity LiOH HCl, essential remanufacturing reducing acid consumption via recycling. High densities leakage, leakage as low 0.03%, though hydronium hydroxide in BMED remains high at 11–20%. Our analysis projects production costs between USD 1.1 3.6 per kilogram, significantly lower than prices. Optimal SED conditions are identified, emphasizing need control proton transport improve cobalt–lithium separation enhance cost efficiency.
