Prediction of The Chromium (III) Separation From Acidic Salt Solutions On Nanofiltration Membranes Using Donnan And Steric Partitioning Pore (DSP) Model

Abstract: This paper presents experimental and modelling analysis of the application of nanofiltration for separation of chromium (III) from acidic salt solution. In the studies commercial nanofiltration HL membrane has been used. The experimental results have been interpreted by, based on the extended Nernst-Planck equation, Donnan and Steric Partitioning Pore (DSP) model. The obtained results showed satisfactory agreement between experimental and modelling data for the pressure range 10-24 bar and different concentrat… Show more

“…In 2019 Nair et al [43] explained the effect of pH on flux variation with the use of the Spiegler-Kedem and Steric-Hindrance-Pore models. Bowen et al [44][45][46][47] proposed the Donnan-Steric partitioning model (DSPM), which has also been used by others [48][49][50][51][52][53][54] with fairly good results. Xu et al [55] investigated temperature influences on the retention of fourteen kinds of pharmaceuticals and personal care products by NF membranes and predicted their performances at given feed temperatures with the use of refined DSPM and a Dielectric-Exclusion model incorporated with temperature functions.…”
