Methylene Blue Kit
The Methylene blue dye test is especially designed to determine the capacity of a clay to absorb cations from a solution, and thereby predict how the clay will react in its intended use. The clay may be component of a drilling fluid, a binder in foundry sand, or clay used for some other purpose. The Methylene Blue Test is based on the property of clays known as Base Exchange capacity; That is, clays can exchange some of their ions for the ions of certain other chemicals. The number of ions available for this exchange varies with different types of clay. Western Bentonite, for example, has more Base Exchange capacity than Southern Bentonite. However, only the reactive portions of the clays are involved in the Base Exchange process. Picture above is the Methylene Blue Adsorption Kit with 220 Volt.
