Description of key information

Tellurium exists mainly as Te(IV) and Te(VI) in natural waters and geological samples and its geochemistry is considered comparable to that of selenium.In the oxidative zone of weathering at or near the earth's surface, tellurium compounds are transformed to tellurites (Te03 2-) from tellurides (Te2-) through the normal pH range of 3-8.At relatively high, but feasible, oxidation potentials, tellurites are oxidized to tellurates (Te04 2-) in alkaline environments (pH 6-8.5).
