Aqueous Dissolution and Recovery of Poly(Vinyl Alcohol) in Multilayer Film

ChemSusChem, Volume 19, Issue 10, 27 May 2026.
Schematic of a water‐based recycling process for PVOH/PBAT‐PLA tri‐layer films, showing selective PVOH dissolution, process condition screening, and recovery of both polymer fractions. In this work, solvent‐based recycling was applied to a multilayer film of PBAT‐PLA and PVOH, where the dissolution conditions were optimized and the reusability of the ...

PTSA (pressure and thermal swing adsorption) method to remove trihalomethanes from drinking water

, 1997
It has been widely recognized that trihalomethanes (THMs) in drinking water pose a risk to human health. THMs can be removed to a certain extent by the conventional point-of-use (POU) unit which is composed of activated carbon (AC) and microfilter.
