Abstract

Karbon aktif dan TiO2 mereduksi SO2 melalui proses adsorpsi dan fotokatalitik. Kedua senyawa ini memiliki efektivitas adsorpsi rendah. Untuk meningkatkan aktivitas adsorpsi dilakukan kombinasi teknik adsorben dan fotokatalitik sehingga adsorpsi dapat optimal. Kombinasi dilakukan dengan membuat komposit karbon aktif/TiO2. Batubara dan semi-kokas dicampur dengan perbandingan 7:3 kemudian TiO2 ditambahkan dengan konsentrasi 1, 3, 6, 9 dan 15%. Karbon aktif/ TiO2 dikarbonisasi pada suhu 600 °C selama 1 jam dan diaktivasi pada suhu 900 °C selama 1 dan 2 jam di bawah aliran gas nitrogen. Hasil analisis fourier-transform infrared (FTIR) spectroscopy menunjukkan intensitas serapan gugus fungsi C=O naik sebesar 49,5% pada karbon aktif/TiO2 6% selama 1 jam dan 33,2% pada karbon aktif/TiO2 3% selama 2 jam. Gugus fungsi basa C=O mereduksi gas SO2 yang bersifat asam. Hasil X-ray diffraction (XRD) ditemukan kristal TiO2 anatas dan rutil. Koeksistensi kristal anatas dan rutil lebih efektif daripada anatas dan rutil fase tunggal. Hasil penelitian ini menunjukkan bahwa karbon aktif/TiO2 meningkatkan aktivitas gugus fungsi permukaan karbon aktif dan membentuk kristal TiO2 anatas dan rutil secara bersama.

Abstract

Sphalerite is one of the sulfide ore minerals that serves as the raw material for zinc sulfide concentrate (ZnS). Sphalerite in nature needs to be processed through a concentration process to become a high-value ZnS concentrate. The determination of zinc (Zn) content in the ZnS concentrate is carried out using complexometric methods, referring to the modified ISO 13658:2000 method in the preparation stage. In this research, the validity of the test results was conducted using several parameters, including precision testing (repeatability and reproducibility), accuracy (recovery and test result comparison with CRM value), and measurement of relative uncertainty in Zn content determination in ZnS concentrate using the modified ISO 13658:2000 method, it is conducted by two analysts. Certified reference material (CRM) O354 with a Zn content range of (49,30±2,46)% was used as a sample in this research. Zinc content in CRM O354 by Analyst X obtained 49.30% with RSD=0.37% and range of Recovery=(99.5-100.6)%, while Analyst Y obtained 49.03% with RSD=0.64% and range of Recovery=(98.1-99.9)%. Mean of results of the determination of Analyst X and Analyst Y is 49.13% with an uncertainty expanded by 1.90% so, Zn content is obtained at (49,13±1,90)% and the relative uncertainty is obtained at 3.87%. The minimum criteria for precision testing in terms of repeatability are RSD<2/3 CV Horwitz, and for reproducibility (F-test), Ftest<Ftable, for accuracy testing in terms of Recovery=(98-102)%, inter-analyst comparison, and test result comparison with CRM value (t-test), ttest<ttable as well as the minimum criteria for measurement of relative uncertainty<5%. Therefore, the test results of the modified ISO 13658:2000 method for Zn determination in ZnS concentrate have fulfilled all the validity parameters of the test results.

Abstract

Lead sulfide (PbS) concentrate is derived from the sulfide mineral galena. In nature, galena must first undergo a concentration process to become PbS concentrate. The determination of lead (Pb) content in the PbS concentrate is carried out using complexometric methods, referring to the modified ISO 13545:2000 standard during the preparation stage. In this research, the validity of the test results was assessed using several parameters, including precision test (repeatability and reproducibility), accuracy (%recovery) and estimation of measurement uncertainty. Certified reference material (CRM) Pb353, with a Pb content range of 58.20-64.33% was used as a sample in this study. The results showed an average Pb content of 61.11% for analyst A and 61.00% for analyst B in CRM Pb353. The research successfully met the precision testing requirements for repeatability (RSD 0.46% for analyst A and 0.39% for analyst B < 2/3 coefficient variance (CV) Horwitz 1.44%) and reproducibility (F-test 1.34 < F-table 4,28 and P-value 0.37 > significance level 0.05). Accuracy was also demonstrated with %recovery (analyst A 9.06–100.53% and analyst B 99.23–99.98%), as well as the estimation of measurement uncertainty (μrelative 2.27% < 5%). Therefore, the determination of Pb content using complexometric methods with modified preparation techniques in the PbS concentrate ensures the validity of the results.
