OPTIMASI KINERJA ANALITIK PADA PENENTUAN KADAR FOSFOR SEBAGAI P2O5 PADA ABU BATUBARA DENGAN METODE SPEKTROFOTOMETER VISIBLE
Abstrak: The research on
optimization of analytical performance in the determination of phosphorous as
P2O5 content in the coal ash with visible spectrophotometer method has been
done. In this research was conducted validation visible spectrophotometer
method to establish the levels of phosphorus in coal ash. Validation parameters
used in this research were accuracy, precision, linearity, LOD, LOQ and
ruggedness methods. From the result of this research, accuracy was stated in
percent recovery, precision was stated as a RSD percent, withthe equation of
linearity as y=0,1768x - 0,0076. From the equation, it will be obtained LOD and
LOQ values. And endurance test methods that varied the length of it digest
time. From the results it can be concluded that the determination of phosphorous
content in the coal ash using visible spectrophotometer method has good
precisionand accuracy, and able to be justified
