Abstract

Telah dilakukan penelitian mengenai perbandingan metode permanganometri dan serimetri dalam menentukan kadar besi(II). Penelitian ini dilakukan untuk mengetahui metode titrasi yang lebih efektif dalam menentukan kadar besi(II). Penetapan kadar besi dilakukan pada larutan Fe (II) yang telah diketahui konsentrasinya. Larutan Fe (II) yang digunakan adalah larutan dengan konsentrasi Fe (II) sebesar 5 ppm. Pengukuran dilakukan dengan mentitrasi larutan Fe (II) 5 ppm dengan menggunakan dua metode berbeda yakni permanganometri dan serimetri. Pada metode permanganometri larutan Fe (II) 5 ppm dititrasi menggunakan larutan permanganat, sedangkan pada metode serimetri larutan Fe (II) 5 ppm dititrasi menggunakan Larutan Ce (IV). Kadar besi yang terukur dengan metode permanganometri sebesar 4,8561 ppm dengan % recovery sebesar 97,122%, sedangkan kadar besi yang terukur dengan metode serimetri sebesar 4,8649 ppm dengan % recovery sebesar 97,298%. Hal ini menunjukkan bahwa keduanya merupakan metode yang sama baik dalam menentukan kadar Fe (II). ============================================================ Observation about comparison methods of permanganometry and serimetry to determine the concentration of iron (II) has been done. This study was conducted to obtain the titration method which is more effective to determine concentration of iron (II). The concentration of iron (II) is observed on the solution of Fe (II) with a known concentration. The iron (II) concentration of solution is 5 ppm. Measurements were made by titrating a solution of Fe (II) 5 ppm by using two different methods that’s named permanganometry and serimetry. In the permanganometry method, the solution of 5 ppm Fe (II) is titrated using the solution of permanganate, while the serimetry method, solution of Fe (II) is titrated using the solution of Ce (IV). The Iron Concentration which is measured by the permanganometry method is 4.8561 ppm and % recovery as 97.122%, while the iron concentration which is measured by the serimetry method is 4.8649 ppm and % recovery as 97.298%. This shows that both methods are equally good in determining the content of Fe (II).
