D2EHPA present in n-hexane is an effective, efficient and highly selective carrier for the transport of MG dye through BLM. Maximum transport 88% was observed at 0.24M concentration of D2EHPA in the membrane phase and 7 moles concentration of acetic acid in the receiving phase after 300 min. The effect of parameters influencing the transport of MG dye such as pH and concentration of dye in the donor solution, extractant concentration in the membrane phase, nature of the organic solvent, the composition of receiving phase, stirring speed and kinetics parameter were elucidated. First order irreversible reaction kinetics k1 and k2 were applied for the transport of MG dye from aqueous phase BLM phase and BLM to acceptor phase.  The accumulation of MG in  BLM phase and the rate controlling step under different experimental conditions were also discussed. Finally, the proposed liquid membrane was effectively applied for MG dye transport from textile wastewater.
