Full Description

This method is for determining the pH of, and iron and copper concentrations in, refinery waters. The data may be used to gauge the extent of corrosion caused by refinery waters. Copper and iron are determined at levels of 0.1 µg/mL and higher using Atomic Absorption Spectrometry (AAS). The metals may be present as single dissolved ions, as complex ions with cyanide or other complexing agents, or as part of the suspended solids that are often present in such samples. Ammonia, hydrogen sulfide, hydrogen cyanide and organic matter do not interfere with this test. The pH of the water is determined because it usually correlates with the extent of corrosion.
