Location: Group 16, Period 5
Storage & Handling: Keep tightly sealed when not in use. Store and use at 20 ± 4°C. Do not pipet from container. Do not return portions removed for pipetting to container.
Chemical Compatibility: Soluble in HCl, HNO3, H3PO4, H2SO4 and HF aqueous matrices and water. It is stable with most inorganic anions and cations. Avoid mixing HCl matrices with elements forming insoluble chlorides such as Ag+. When fluorinated and/or under acidic conditions precipitation is typically not a problem at moderate to low concentrations.
Stability: 2-100 ppb levels stable for months alone or mixed with other elements at equivalent levels in 1% HNO3 / LDPE container. 1-10,000 ppm solutions chemically stable for years in 1-5% HNO3 / LDPE container.
Te Containing Samples (Preparation & Solution): Metal (soluble in solutions of alkali hydroxides or a 1:1:1 mixture of H2O, H2SO4, HNO3); Oxides (TeO2 is soluble in HCl and the alkali hydroxides. TeO3is soluble in hot concentrated solutions of the alkali hydroxides.); Minerals and alloys (acid digestion with HNO3or HNO3 / HF); Organic Matrices (Vegetable Matter - dry ash 100 g of the well-ground and mixed vegetation into a concentrated solution of 25 g of magnesium nitrate and magnesium oxide. Dry, ignite and muffle until the ash is a uniform gray color).
