Spectral determination of thallium and zinc by chloride sublimation method

It is investigated kinetics of thallium and zinc intermission in plasma of the coal arch at the presence of various reagents. It is shown, that the most effective reagent for thallium and zinc determination are chlorides of ammonium or cupper with a coal powder. Results of experimental researches are proved by thermodynamic calculations. By atomic-emission spectral method with application of thermochemical reactions of chlorination was analysed clay rocks and soils. The relative standard deviation is 15-18 %. A limit of determined concentration is 10²-10⁴ %.
