Her innovative approach has led to the development of a unique method that enhances the accuracy of hardness measurements in liquid samples.
Latest Patents
Sharon S. Sloat holds a patent for a method titled "Calcium and magnesium specific hardness method using aluminum chelate." This method involves preparing a liquid sample for measuring its calcium and magnesium hardness by adding an aluminum chelate, specifically aluminum disodium (cyclohexylenedinitrilo) tetra-acetic acid. The process maintains the pH of the sample between 5 and 8, effectively eliminating interference from iron or copper ions without the use of harmful substances. The pH is then adjusted to between 9.5 and 11 to insolubilize aluminum ions. A magnesium chelate is subsequently added to exchange calcium ions, releasing an equivalent number of magnesium ions, followed by the addition of a dye indicator that forms a colored complex with magnesium ions. The final measurement of calcium plus magnesium hardness can be conducted through titration or spectrophotometry.
