WebIn this review, the most relevant steps towards the use of non-toxic solvents in membrane preparation are reported, focusing particular attention on the non-solvent induced and temperature induced phase separation (NIPS and TIPS) techniques. Supercritical CO 2 (ScCO 2) and ionic liquids (ILs) are promising examples of benign solvents, and their ... WebMost commonly used solvent vapors have “Permissible Exposure Limits” (PELs) or allowable amounts in the air. Most of these limits are based on average 8-hour exposures – a few are peak or ceiling limits. The lower the limit, the more toxic the solvent is. Examples of PELs for common solvents: acetone – 750 ppm xylene – 100 ppm
