Greetings, all:
Although the utilization of clays for heavy metal detoxification has not been fully studied for human use, there are quite a few scientific studies that demonstrate the ability of clays to bind heavy metals:
"Conclusions. Our results clearly show that the addition of clay minerals, especially of Na-bentonite and Ca-bentonite, decreased the extractability of four metals during incubation. The decreased metal extractability was accompanied by an increase of soil respiration, Corg mineralization, microbial biomass C, and inorganic N and a decrease of metabolic quotient (qCO2), showing positive effect of clay mineral addition on soil biological parameters.
Recommendations and Outlook. The use of Na-bentonite and Ca-bentonite is promising tool for reduction the extractability and possible toxicity of heavy metals in sewage sludge-contaminated soil. Therefore, the soils polluted with heavy metals may be ameliorated by addition of clay minerals, especially Na-bentonite and Ca-bentonite."

| Bentonites accepting low adamant content, accept been begin to be acceptable catalytic agents in petroleum refining. The bentonites accepting Ca and / or Mg as changeable ions are acceptable decolourizers. Bentonites can blot baptize to a greater admeasurement than accustomed artificial clays. Fuller's earth, on the added hand, is non-plastic or semi-plastic in character. It has a foliated structure. |

| I'm wondering what kind of steps would have to be taken to begin human research. I wish I was well connected some some of the local universities. What kind of major corporation might want to sink some money in to this kind of project?? |
