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).
