Putri, Bertha Aditya (2018) Pengaruh pH dan Konsentrasi Tiosianat pada Fasa Umpan Terhadap Transpor Ion Tiosianat Melalui Polymer Inclusion Membran (PIM) Aliquat 336-Cl/1-Dekanol. Sarjana thesis, Universitas Brawijaya.
Abstract
Konsentrasi dan pH larutan ion tiosianat dalam fasa umpan menentukan efektivitas transpor ion tiosianat melalui PIM. Tujuan dari penelitian ini adalah untuk mempelajari pengaruh pH dan konsentrasi larutan ion tiosianat pada fasa umpan terhadap transpornya melalui PIM. PIM dibuat dari campuran polimer dasar PVC, ekstraktan aliquat 336-Cl, dan pemlatis 1-dekanol. Fasa umpan diisi 100 mL larutan tiosianat pada pH 1; 2; 4; 6; dan 8, dengan berbagai konsentrasi 20; 40; 60; 80; dan 100 mg/L. Fasa penerima diisi 100 mL larutan NaCl 1M. Kedua fasa diaduk selama 180 menit dengan kecepatan 150 rpm. Larutan pada kedua fasa diambil sebanyak 1 mL setiap 30 menit. Konsentrasi ion tiosianat dalam cuplikan dianalisis secara spektrofotometri menggunakan pereaksi besi(III) klorida pada panjang gelombang 460 nm dengan membentuk senyawa kompleks besi(III)tiosianat berwana oranye. Hasil penelitian menunjukkan bahwa transpor ion tiosianat terjadi secara optimal pada pH 2 dan pada konsentrasi ion tiosianat 80 mg/L dengan nilai fluks awal 6,432x 10-2 mg/min.cm2 dan efisiensi transpor sebesar 42,16 %.
English Abstract
The pH and concentration of thiocyanate ions solution determine the effectiveness of its transport through PIM. The purpose of this study was to study the effect of pH and concentration of thiocyanate ions solution in the feed phase to its transport through PIM. PIM was prepared from a mixture of a PVC base polymer, a aliquat 226-Cl extractan, and a 1-decanol plasticizer. The feed phase was filled by 100 mL thiocyanate solution at pH 1, 2, 4, 6, and 8, and at concentration of 20, 40, 60, 80, and 100 mg/L. The receiving phase was filled with 100 mL of 1 M NaCl solution. Both phases were stirred for 180 min at 150 rpm. The solutions in both phases were taken as much as 1 mL every 30 minutes. The concentration of thiocyanate ions in the samples was analyzed by spectrophotometric method using iron (III) chloride at a wavelength of 460 nm based on the formation of iron (III) thiocyanate complex. The result showed that transport of thiocyanate ion was optimally occurred at pH 2 and at concentration of 80 mg/L with initial flux value was 6.432 x 10-2 mg/min.cm2 and transport efficiency was 42.16%.
