- A new gravimetric method, based on reduction of tellurites and tellurates to elementary rellurium in 3N-HCI solutions by amidinothiourea and hydrazine, has been developed. Au (III) is separated from tellurium by extract ion with diethyl ether in 1.6 M .HCI. Hg (II), Cu(u), and Ag(I) are masked with potassium iodide. thiourea, and HCI, respectively. Other cations and anions have been found not to interfere. Accuracy and relative standard deviation are ± 0.3% and ± 0.22%. respectively.
