Feasibility analysis of SO2 absorption using a hydrophilic ceramic membrane contactor
Hydrophilic ceramic membranes would be potential candidates for membrane gas absorption if they could be applied to appropriate separation processes. This study highlights a novel concept for the practical implementation of SO

it can be inferred that the hydrophilic α-Al
