AN120: Determination of Calcium and Magnesium in Brine Be the first to rate this application

calcium magnesium brine


To prevent membrane poisoning, new membrane technology in chlor-alkali cells requires feed brine that is relatively free of alkaline earth metals.This Application Note describes a method for determining low μg/L amounts of calcium and magnesium in a 30% sodium chloride brine by ion chromatography. A MetPac column is used to concentrate calcium and magnesium from the brine, which is then separated on an IonPac CS12A cation-exchange column and detected by suppressed conductivity detection. AU158 updates this method to achieve 10 ppb manganese by concentrating 10 times more sample.
