Oktavianto, RizkiTri (2016) Pengaruh Konsentrasi Eluen dan Volume Sampel pada Ekstraksi Fasa Padat Zn(II) Menggunakan Biomassa Azolla microphylla-Alginat dengan Metode Kolom. Sarjana thesis, Universitas Brawijaya.
Abstract
Penelitian ini mengkaji pengaruh konsentrasi eluen (HCl) dan volume sampel pada ekstraksi fasa padat menggunakan biomassa Azolla microphylla-alginat. Ekstraksi fasa padat menggunakan kolom 10 x 1 cm dan biomassa A. microphylla-alginat berukuran 20-40 mesh sebanyak 1 gram. Percobaan adsorpsi Zn(II) dilakukan dengan mengalirkan larutan Zn(II) 1 mg/L sebanyak 50 mL dan recovery pada variasi konsentrasi 0,2 M, 0,4 M, 0,6 M, 0,8 M, dan 1 M. Pada kajian pengaruh volume sampel, percobaan adsorpsi dilakukan dengan variasi volume sampel 25 mL (2 mg/L); 50 mL (1 mg/L); 75 mL (0,66 mg/L); 100 mL (0,5 mg/L); dan 125 mL (0,4 mg/L). Prosentase adsorpsi sebesar 99,9 % dan prosentase optimum recovery sebesar 79,4 % di konsentrasi 0,8 M. Volume sampel pada penelitian ini tidak berpengaruh terhadap ekstraksi fasa padat Zn(II) menggunakan biomassa A. microphylla-alginat.
English Abstract
This research studied about effects of eluent (HCl) concentration and sample volume on solid phase extraction of Zn(II) using Azolla microphylla-alginate biomass. Solid phase extraction was performed using column with a height of 10 cm and a diameter of 1 cm filled with 1 g of A. microphylla-alginate biomass of 20-40 mesh. Adsorption experiments were carried out by passing 50 mL of 1 mg/L Zn(II) solution through the column. Zn(II) which was retained in the column was eluted with 5 mL HCl solution with various concentrations of 0.2 M; 0.4 M; 0.6 M; 0.8 M; and 1 M. In the study of sample volume effect, adsorption experiments were conducted with variations in sample volume of 25 mL (2 mg / L); 50 mL (1 mg / L); 75 mL (0.66 mg / L); 100 mL (0.5 mg / L); and 125 mL (0.4 mg / L). The results showed that the adsorption was 99.8 %, and the optimum concentration of the eluent solution was 0.8 M HCl with the percentage of Zn(II) recovery was 79.4 %. Sample volumes wasn’t significantly affected the solid phase extraction of Zn(II) using A.microphylla-alginate biomass.
