    Abstract: In forward osmosis (FO), reverse salt diffusion not only reduces water flux but also increases the requirement of
    draw solute replenishment. FO would be very desirable if there was no draw solute leakage and the recovery of draw solutes was
    easy. In this study, a novel draw solute, ethylenediaminetetraacetic acid (EDTA)-2Na coupled with Triton X-100 was explored
    with the aim of minimizing reverse salt diffusion. The results indicated that reverse salt diffusion achieved zero the first time when
    using 0.1 M EDTA-2Na coupled with 0.5 mM Triton X-100 as draw solution and DI water as feed solution. A water flux of 4.6
    L/m2 h was reached when 35 g/L NaCl of model seawater was used as the feed solution and 1 M EDTA-2Na coupled with 0.5
    mM Triton X-100 was used as the draw solute. Moreover, a nanofiltration (NF) membrane was employed to recover the draw
    solute, achieving a high rejection of 95% due to the high charge and large size of the draw solute.
