| 總結: | The analytical methods are generally high-cost, time and chemicals consuming. The usage of
these chemicals makes the laboratory becomes the source of environmental pollutions. Flow
Injection Analysis (FIA) method is a solution for reducing the high usage of chemicals since
its measurement is less time consuming and it does not need to reach the real system
equilibrium. An analysis protocol for sulfate ion using one drop FIA method with
spectrophotometric detection technique using optical fiber equipment was developed and
evaluated. The evaluation results in a high analytical performance of the method, shown by
the reproducibility values of 7.14% and 1.96% for concentration of 25 ppm and 125 ppm,
respectively. Calibration curve showed a good linearity at the concentration range of 25 to
125 ppm with the approximate correlation value of 1. This method was applied to analyze
the sulfate ion concentration in water from Jatiluhur dam. |
