Ligand ditizon is one of the ligands which can absorb zink metal at low concentration, to be more efficient then used the liquid membrane emulsion technique which enables separation without going through the process of precipitation. Variations of concentration used is 1:3 v/v, 1:1 v/v and 3:1 v/v. Optimum absorption occurs at concentrations 1:3 v/v are 90.77%. Variations of liquid membrane emulsion duration used is 5 minute, 10 minute and 15 minute. Optimum absorption at duration 5 minute are 50.22%. Optimum absorption on the interaction between concentration and liquid membrane emulsion duration are 43.73% obtained F (392.76) &gt;&nbsp; Ftable (14.80).</em></p> <p><strong><em>Keywords:</em></strong><em> ditizon, absorption, emulsion liquid membrane</em></p&gt;}, number={1}, journal={EduMatSains : Jurnal Pendidikan, Matematika dan Sains}, author={Harefa, Nelius}, year={2018}, month={Jul.}, pages={57-68} }
