Abstract
The invention relates to the technical field of chemistry and in particular discloses a one-time digestion constant volume device through gold purity detection. The one-time digestion constant volume device through gold purity detection comprises a reagent bottle arranged in heating equipment, and is characterized in that a volume scale tube of which two ends are open and interior is hollow is attached to an inner wall of the reagent bottle, wherein a condenser pipe is arranged on the reagent bottle; the condenser pipe is tightly connected with a bottle opening of the reagent bottle through a grinding opening in the bottom end. The one-time digestion constant volume device is simple in structure, safe to operate, reasonable in design and integrates the functions of digesting, removing nitrate and enabling the volume to be constant, and loss of volatile elements is effectively avoided, so that the detection result is accurate, and the efficiency of the detection operation is accelerated.
Description
Technical field
The present invention relates to technical field of chemistry, particularly a kind of golden purity detecting is once cleared up volume fixing device.
Background technology
At present, the refining purifying of gold and purity detecting generally adopt the method for the thick gold of chloroazotic acid heating for dissolving.During the molten gold of chloroazotic acid, with acid gas, produce, contain in a large number HCl, NO, NO
2and the acid gas of a small amount of HAuCl is excessive, contaminated environment not only, etching apparatus, the loss that has also increased gold.
And the routine operation of golden purity detecting is, in beaker, gold is dissolved in chloroazotic acid, after dissolving completely, catch up with nitre, then with watery hydrochloric acid, transfer to constant volume in volumetric flask, in this process, except volatilizing, above-mentioned acid gas causes golden loss, in operating process, also need sample to shift, easily cause the loss of product, cause testing result inaccurate.
Summary of the invention
The present invention is in order to make up the deficiencies in the prior art, a kind of handling safety is provided, detected golden purity detecting accurately and once clear up volume fixing device.
The present invention is achieved through the following technical solutions:
A kind of golden purity detecting is once cleared up volume fixing device, comprise the reagent bottle being placed in firing equipment, it is characterized in that: the volume markings pipe that is attached with both ends open, inner hollow on described reagent bottle inwall, condenser pipe is installed on reagent bottle, and condenser pipe is closely connected with reagent bottle bottleneck by the ground of bottom.
The present invention installs condenser pipe on the reagent bottle of clearing up for metal, the cooling collection of acid gas by condenser pipe to volatilization, effectively reduce golden loss, make the testing result of golden purity more accurate, meanwhile, volume markings pipe is set in reagent bottle, volume markings pipe inner hollow, liquid in reagent bottle can enter in volume markings pipe, measures the volume of liquid by volume markings pipe, effectively reduces because of the excessive measuring error causing of reagent bottle diameter.
More excellent scheme of the present invention is:
Described condenser pipe top is provided with the pipeline that connects air exhauster, after gold is cleared up completely, by air exhauster, reagent bottle is drawn gas, and improves and catches up with nitre speed.
Described reagent bottle is arranged with insulating collar outward, is convenient to the reagent bottle of taking after heating, effectively prevents from scalding.
The present invention is simple in structure, and handling safety is reasonable in design, integrates and clears up, catches up with nitre, constant volume, effectively prevents the loss of Volatile Elements, makes testing result more accurate, has accelerated the efficiency of testing.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Fig. 1 is structural representation of the present invention.
In figure, 1 firing equipment, 2 reagent bottles, 3 volume markings pipes, 4 condenser pipes, 5 grounds, 6 pipelines, 7 insulating collars.
Embodiment
Accompanying drawing is a kind of specific embodiment of the present invention.This embodiment comprises the reagent bottle 2 being placed in firing equipment 1, on described reagent bottle 2 inwalls, be attached with the volume markings pipe 3 of both ends open, inner hollow, condenser pipe 4 is installed on reagent bottle 2, and condenser pipe 4 is closely connected with reagent bottle 2 bottlenecks by the ground 5 of bottom; Described condenser pipe 4 tops are provided with the pipeline 6 that connects air exhauster; The outer insulating collar 7 that is arranged with of described reagent bottle 2.
Golden sample and chloroazotic acid are added in reagent bottle 2, condenser pipe 4 is installed on the port of reagent bottle 2, ground 5 by condenser pipe 4 is combined closely both, make the logical cold water of condenser pipe 4, then open firing equipment 1, for clearing up the golden sample of reagent bottle 2, to the complete molten cold water of closing of golden sample, by the pipeline 6 on condenser pipe 4 terminations, connect air exhauster, open air exhauster, to reagent bottle, nitre is caught up with in 2 heating.
After catching up with nitre to finish, close firing equipment 1, remove condenser pipe 4, in reagent bottle 2, add watery hydrochloric acid constant volume, according to volume markings pipe 3, accurately read respective volume parameter, be convenient to calculate the purity of golden sample; Because the caliber of volume markings pipe 3 is less, be positioned at its inner liquid levels and read comparatively accurately, improved the accuracy detecting.
