Magnesium is a widely occurring natural element and is found in most water supplies. Magnesium salts contribute to the hardness of water and higher levels of magnesium will be found therefore in hard water areas. Scale formation in heating and steam raising equipment is promoted by the presence of magnesium salts in the water. Magnesium salts do however have a lower scale forming tendency than calcium salts.
The Palintest Magnecol test provides a simple means of measuring magnesium levels in water over the range 0–100 mg/l Mg.
The Palintest Magnecol test is based on a simple colorimetric procedure. Magnesium reacts with an organic reagent to produce an orange-coloured complex. The reagent itself is yellow and therefore over the range of the test a series of colours from yellow through to orange are produced.
The colour produced in the test is indicative of the magnesium concentration and is measured using a Palintest Photometer.
