Abstract BACKGROUND In this study, the transport of Cr (VI) ions was investigated with electroanalytical approach, called electro‐membrane extraction (EME), by using a supported liquid membrane (SLM). RESULTS Aliquat 336 and Celgrad 2500 were used as a carrier and support material, respectively. Chromium (VI) ions were transferred from sample solution containing target analyte to extractant solution at low potential values (10–50 V) and with different current values (0.1–0.4 A). CONCLUSION The following parameters such as carrier change, carrier concentration effects, solvent change effect were investigated and Cr(VI) transport was achieved with 54.73% recovery in 100 min at optimum conditions. In the EME‐SLM process, Danesi mass transfer model was used to calculate the kinetic data, rate constant, flux, permeability, and recovery, for each parameter examined. © 2021 Society of Chemical Industry (SCI).
