During penetrating property, to generally analyze in sample210Po.210Po is present in inorganic matters and Organic substance,210The compound of Po compares
Readily volatilized.
Generally exist210During the collection of Po solid sample, it is necessary first to concentrated acid (containing nitric acid, hydrochloric acid, perchloric acid, hydrogen
The solution such as fluoric acid) carry out the wet type ashing under conditions of 100 DEG C of pre-treatment, i.e. temperature to sample, the purpose of pre-treatment be 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 substance is respectively processed.For containing in sample210Po inorganic matters, nitric acid, hydrochloric acid have well clears up effect
Really, wherein silicate can use hydrofluoric acid treatment.But contain in sample210Po Organic substance generally needs perchloric acid and hydrogen peroxide repeatedly
Process, process repeatedly and not only the time is expended while a large amount of acid solutions are also consumed, 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.
Content of the invention
(1) goal of the invention
Instant invention overcomes prior art consumes a large amount of acid solutions, sample need to be processed repeatedly, temperature strictly must be controlled
Make and exist the deficiency of certain risk, there is provided a kind of simple and convenient, acid solution consumption is few, and safe operation process can
Lean on, and can quickly realize the device and method that the oxidation of polonium is collected.
(2) technical scheme
In order to solve the problems of prior art, the technical scheme that the present invention 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

Collection method is aoxidized using the polonium of the device, is comprised the following steps：
(1) solid sample containing polonium is positioned on the glass boat in glass tubing；
(2) oxygen is passed through into glass tubing, is started to glass tube heating by resistance furnace, by temperature controller control temperature
Degree；
(3) gas that reaction is produced is collected by absorbing liquid.
Further, the temperature controller carries out temperature control using the regulation and control method of temperature-gradient method.
Further, the step collects, as absorbing liquid, the gas that reaction is produced using hydrochloric acid.
(3) beneficial effect
Apparatus of the present invention simple structure, and easily operated；Temperature controller can make sample fully react using temperature-gradient method,
And it is not required to repetitive operation.Compared with traditional method：10g sample, being collected with traditional approach needs 20h or so, consumes acid solution 200ml
Left and right, only needs 3h or so with the present invention, consumes acid solution 50ml or so；Acquisition time is greatly improved, reduces acid solution
Consumption.
The present invention preferably can ensure to collect during safe operation, it is to avoid the safety that traditional polonium collection method is present
Hidden danger, it is achieved that safely and efficiently polonium collection method.
