During penetrating property, generally to be analyzed in sample210Po。210Po is present in inorganic matters and Organic substance,210The compound of Po compares
It is readily volatilized.
Generally exist210During the collection of Po solid samples, it is necessary first to concentrated acid (containing nitric acid, hydrochloric acid, perchloric acid, hydrogen
The solution such as fluoric acid) the wet type ashing under conditions of 100 DEG C of pre-treatment, i.e. temperature is carried out to sample, the purpose of pre-treatment is by sample
In product210Po enters solution after changing into ionic state.Contain210Po changes into the solution example of ionic state to be needed to containing210Po is inorganic
Thing and contain210Po Organic substances are respectively processed.Containing in for sample210Po inorganic matters, nitric acid, hydrochloric acid has clear up well effect
Really, wherein silicate can use hydrofluoric acid treatment.But contain in sample210Po Organic substances generally need perchloric acid and hydrogen peroxide repeatedly
Process, process repeatedly and not only the time is expended while also consuming a large amount of acid solutions, and the ignition point of perchloric acid is than relatively low, wet type ashing
During must strict temperature control, will otherwise catch fire, with potential safety hazard.
The content of the invention
(1) goal of the invention
This utility model overcome prior art consume a large amount of acid solutions, sample need to be processed repeatedly, must be tight to temperature
Lattice are controlled and there is the deficiency of certain risk, there is provided a kind of simple and convenient, acid solution consumption is few, safe operation process
It is reliable, and can quickly realize the device of the oxidation collection of polonium.
(2) technical scheme
In order to solve the problems of prior art, the technical scheme that this utility model is provided is as follows：
Polonium oxidation collection device in a kind of solid sample, it is characterised in that the device includes glass boat, glass tubing, thermometric
Device, temperature controller, resistance furnace and Drexel bottle, glass boat are placed in glass tubing, and temperature measuring equipment, thermometric dress are equipped with outside glass tubing
Put and be connected with temperature controller, glass tubing and temperature measuring equipment are placed in resistance furnace, the outlet side of glass tubing and Drexel bottle connect.
Further, described temperature measuring equipment is thermocouple.
Further, described glass boat is quartz glass boat, and glass tubing is quartz glass tube.
Further, described resistance furnace is tube type resistance furnace.
Further, described Drexel bottle is built-in with absorbing liquid.
Further, described absorbing liquid is hydrochloric acid solution.
(3) beneficial effect
This utility model apparatus structure is simple, and easily operated；Temperature controller temperature-gradient method can be such that sample fully reacts,
And it is not required to repetitive operation.Compared with traditional method：10g samples, being collected with conventional apparatus needs 20h or so, consumes acid solution 200ml
Left and right, only needs 3h or so with this utility model, consumes acid solution 50ml or so；Acquisition time is greatly improved, acid is reduced molten
The consumption of liquid.
This utility model can preferably ensure to collect during safe operation, it is to avoid traditional polonium collects the safety for existing
Hidden danger, realizes safely and efficiently polonium and collects.
