Mabapi le Tellurium Dioxide
Sephetho se seholo sa ho chesa ha tellurium moeeng ke tellurium dioxide. Tellurium dioxide e ka thatafalloa ho rarolloa ka metsing empa e ka rarolloa ka botlalo ka har'a asiti e matla ea sulfuric. Tellurium dioxide e bontša ho se tsitse ha e na le asiti e matla le oxidant e matla. Kaha tellurium dioxide ke ntho e nang le amphoteric, e ka arabela ho asiti kapa alkaline ka har'a tharollo.
Kaha tellurium dioxide e na le monyetla o moholo haholo oa ho baka ho holofala 'me e chefo, ha e monngoa 'meleng, e ka hlahisa monko (monko oa tellurium) o tšoanang le monko oa konofolo ha e phefumoloha. Mofuta ona oa ntho ke dimethyl tellurium e hlahisoang ke metabolism ea tellurium dioxide.
