Nanoflux, a nanofiltration simulation software, was used to predict the rejection of Co2+ and Ni2+ from a salty multi-element matrix whose concentration is similar to seawater. Orientation simulations prior to filtration experiments were made with Nanoflux in order to predict ionic rejections. Previously, the multi-element matrix solution speciation was studied by JChess. It was shown that the effective membrane charge and the effective membrane thickness, adjusted through the filtration of a single salt NaNO3 solution, could be used to predict the ionic rejections of the multi-element solution for two commercial nanofiltration membranes. The elevated concentration of NaNO3 in the multi-electrolyte solution did not reduce the high ionic selectivity of divalent ions. Predicted values were in good agreement with experimental results at neutral pH of the multi-electrolyte solution. %G English %L hal-00808994 %U https://hal.science/hal-00808994 %~ CEA %~ UNIV-TLSE3 %~ IRSAMC %~ LPT %~ CNRS %~ UNIV-MONTP2 %~ ENSC-MONTPELLIER %~ IEM %~ LPT_PHY %~ DEN %~ INC-CNRS %~ CHIMIE %~ UNIV-MONTPELLIER %~ DEN-MARCO %~ UNIV-UT3 %~ UT3-INP %~ UT3-TOULOUSEINP %~ UM1-UM2 %~ TEST2-HALCNRS
