ГОСТ 4658-73 Ртуть. Технические условия (с Изменениями N 1-6)



Allowed to use another hardware design of the circuit without changing the basic parameters of sublimation of mercury: the speed of evacuation of gases 6−10 DMГОСТ 4658-73 Ртуть. Технические условия (с Изменениями N 1-6)/min, the sublimation temperature of 330−350 °C and calcination 490−510 °C.

Method for determination of nonvolatile residue content based on the sublimation of mercury with subsequent weighing the nonvolatile residue.

For the analysis using a porcelain crucible according to GOST 9147 and quartz according to GOST 19908. For mercury stamps r0 using quartz crucibles for stamps P1 — quartz or porcelain, for grades P2 and P3 — porcelain. The crucible pre-calcined at a temperature of 490−510 °C, weighed at least two times and placed in a desiccator.

Porcelain crucibles are weighed on the scales of the brand of VLA-200 g or other precision weighing 0.0005 g, quartz crucibles — stamps on the scales VLR-20 g or other, ensure the weighing accuracy of 0.00005 g. the Differences of the weighing results must not exceed the permissible error of the weighing 0.0005 g for the balance VLA-200 g and 0.00005 g — for the balance VLR-20 g.

For the result of the weighing of crucibles be the arithmetic mean of the results of the two weighings.

A sample weight of 100 g for mercury marks R1 and r0, 50 g for mercury brand P2 and 10 g for Hg brand P3 is placed in a crucible in a sealed steel chamber and sublime in the installation shown in Fig.

The mercury is distilled off at a temperature of 330−350 °C to until the crucible will not remain 1 to 2 grams of mercury.

Then the crucible with mercury calcined to constant weight at a temperature of 490−510 °C and weighed at least two times.

Discrepancies in the results of the two weighings shall not exceed the mercury brands: r0 — 0,00005 g; R1 — 0.0005 g; P2, P3 — 0.005 g.

For the result of the measurement of the mass of nonvolatile residue be the arithmetic mean of the results of the two weighings.

In processing the results of mass fraction of nonvolatile residue (ГОСТ 4658-73 Ртуть. Технические условия (с Изменениями N 1-6)) in percent is calculated by the formula
