Senyawa pembawa Eugenil oksiasetat disintesis dari eugenol dengan penambahan NaOH dan asam kloroasetat di mana garam yang terbentuk diasamkan dengan HCl. Setelah itu dilakukan pemurnian dengan dietil eter dan NaHCO 3 . Hasil sintesis dianalisis dengan FTIR dan kromatografi gas. Untuk proses transport, fasa umpan menggunakan campuran ion logam Cu(II), Cd(II), dan Cr(III) masing-masing 50 ppm, fasa penerima adalah HCl dengan variasi pH 1 sampai 6. Sedangkan untuk mengetahui selektifitas senyawa EOA dilakukan transport menggunakan variasi massa eugenil oksiasetat yaitu 0,3 gram; 0,5 gram dan 0,7 gram serta blanko. pH dan massa eugenil oksiasetat terbaik digunakan untuk recovery logam krom dari limbah electroplating dengan dua cara yaitu dengan reduksi limbah krom dan tanpa reduksi limbah krom. Untuk mengetahui jumlah logam yang tertransport dianalisis dengan AAS. Hasil yang diuji menunjukkan bahwa eugenil oksiasetat berhasil disintesis dengan kemurnian 100 %. Hasil transport menunjukkan bahwa EOA memiliki selektivitas tinggi terhadap Cr(III) dengan persen transport terbaik 95,17 % yang diperoleh pada pH fasa penerima 1 dan massa eugenil oksiasetat 0,7 gram. Hasil recovery limbah krom tanpa reduksi mampu mentransport sebanyak 5,42 %, sedangkan hasil recovery krom dengan reduksi mampu mentransport limbah krom sebanyak 68,60%.}, issn = {2597-9914}, pages = {12--17} doi = {10.14710/jksa.13.1.12-17}, url = {https://ejournal.undip.ac.id/index.php/ksa/article/view/3558} }
