Abstract
It has been conducted the test methods verification of Fe and SiO2 in industrial water using UV-Vis spectrophotometer at PT Krakatau Steel. Verification parameters tested were linearity, precision, accuracy, and detection limit. The results show the value of linearity, precision, accuracy and detection limits for testing Fe are respectively 0.996; 3.803%; 87.94% and 0.048 mg/L while for SiO2 consecutive tests was 0.998; 2.014%; 100.755% and 0.010 mg/L. The results of test methods verification of Fe and SiO2 meet the requirements and can be accepted as a method for routine testing in the chemical laboratory of PT Krakatau Steel.
