Dialysis

• New method for Li recovery from seawater is proposed using the world-first dialysis. • Li ionic superconductor as the Li separation membrane (LISM) was used. • Only Li ions can permeate the LISM. • The Li recovery ratios to approximately 7% after 72 h with no electrical supply. • Li separation proc

A mathematical model for the mass transfer in a parallel plate countercurrent dialysis system coupled with ultrafiltration operation was developed theoretically and experimentally in this study. The analytical solution was obtained using the Frobenius series method. The influences of retentate and d

Experimental studies have been made on the sorption and diffusion of selected carboxylic acids—acetic acid (AA), lactic acid (LA), oxalic acid (OA) and tartaric acid (TA)—in a strongly basic polymeric membrane NeoseptaAMH at 25°C. The sorption experiments have revealed that the partition coefficient

This work describes the determination of carboxylic acid overall mass transfer coefficients in a circulating flow experimental set-up composed of a flat plate dialyzer and a concentrate reservoir. Sodium acetate and sodium propionate were used as the sodium salts of carboxylic acids. By referring to
