But bentonite clay also contains trace amounts of Chromium, Cadmium, Cesium, and Lithium. all of which are toxic and poison's left alone and unbound. But they are bound to the Bentonite Clay just like the lead, they are not Bio-available.

Kinetics of cesium sorption on illite - ScienceDirect

The extent of this process is dependent on the reversibility of cesium sorp- tion. Recently, COMANS et al. (1991) studied the reversibility of cesium sorption on illite by examining the hysteresis be- tween adsorption and desorption isotherms and the isotopic exchangeability ofsorbed cesium.


Overview of Ceramic Materials. Ceramic materials are inorganic, nonmetallic solids prepared by heating followed by cooling. Traditional ceramics are typically produced using processed natural materials such as clay and sand, while advanced or technical ceramics require …


selected contaminants investigated in this two-volume document include: chromium, cadmium, cesium, lead, plutonium, radon, strontium, thorium, tritium (3H), and uranium. This two-volume report also addresses a void that has existed on this subject in both this Agency and in the user community.

Cerium(IV) oxide - Wikipedia

Cerium(IV) oxide, also known as ceric oxide, ceric dioxide, ceria, cerium oxide or cerium dioxide, is an oxide of the rare-earth metal cerium. It is a pale yellow-white powder with the chemical formula CeO 2. It is an important commercial product and an intermediate in the purification of the element from the ores.

The Use of Barium in Clay Bodies (hazard) -

The presence of barium in clay bodies is sometimes thought to be a health hazard for hypersensitive people. Barium is so very slightly soluble that it is difficult to demonstrate solubility of any material in a simple lab experiment (MSDS sheets even list it as insoluble).

Chromium Compounds Toxicology (hazard) -

Chromium occurs in its metallic state (valence 0), and in valence states 2+ through 6+, but only the trivalent (3+) and hexavalent (6+) are commonly found. Chromium in its 2+ state frequently oxidizes rapidly to 3+ form, and the 4+ and 5+ states are found only as intermediates in the conversion between 3+ and 6+ states.
