Description
技术领域technical field
本发明属于自沉积制源技术领域，具体涉及一种镍箔自沉积制源方法，尤其是一种将210Bi、210Po同时定量自沉积于镍箔的方法。The invention belongs to the technical field of self-deposition source preparation, and in particular relates to a nickel foil self-deposition source preparation method, especially a method for simultaneously quantitatively self-depositing 210 Bi and 210 Po on nickel foil.
背景技术Background technique
210Bi、210Po的测定在核地质系统地球化学找矿、煤炭系统探测煤矿、石油系统油气勘查、环境辐射环境质量评价以及其它领域的研究方面具有极其重要的意义。目前210Bi通常采用沉淀制源总β测量法，需要采用稳定铋示踪，且自吸收难以校正；210Po一般采用银箔自沉积制源α测量法，但是由于回收率不稳定，依赖示踪剂进行回收率校正，放射性同位素示踪剂难以获得且需成本较高，而且银箔只对210Po有效；目前仅有铜箔的210Bi、210Po同时自沉积制源技术，可以实现两核素同时测定，但铜箔对某些干扰元素的允许量有限。因此迫切需要一种简单、稳定的210Bi、210Po同时自沉积制源技术，实现在较宽范围内两核素同时测量。The determination of 210 Bi and 210 Po is of great significance in geochemical prospecting in nuclear geological systems, coal mine detection in coal systems, oil and gas exploration in petroleum systems, environmental radiation environmental quality assessment, and research in other fields. At present, 210 Bi usually adopts the total β measurement method of precipitation source, which requires stable bismuth tracer, and self-absorption is difficult to correct; 210 Po generally uses silver foil self-deposition source α measurement method, but due to the unstable recovery rate, it relies on tracer The radioactive isotope tracer is difficult to obtain and requires high cost, and silver foil is only effective for 210 Po; at present, there is only copper foil 210 Bi and 210 Po simultaneous self-deposition source technology, which can realize two-nuclear Elements can be determined at the same time, but copper foil has a limited allowance for some interfering elements. Therefore, there is an urgent need for a simple and stable 210 Bi and 210 Po simultaneous self-deposition source technology to realize the simultaneous measurement of two nuclides in a wide range.

实施例3：Example 3:
本发明依次包括以下步骤：The present invention comprises the following steps in turn:
第一步、用30mL的0.1mol/L HCl+3.4mol/L NaCl溶液提取溶矿后的酸溶渣，转入100mL容器中，加入1.0g抗坏血酸；Step 1: Use 30mL of 0.1mol/L HCl+3.4mol/L NaCl solution to extract the acid-dissolved slag after dissolving the ore, transfer it to a 100mL container, and add 1.0g of ascorbic acid;
第二步、将容器放入振荡水浴中，控制水浴的温度为95℃，振速为200r/min，振幅20mm，振荡120min后取出。The second step is to put the container into a vibrating water bath, control the temperature of the water bath to 95°C, the vibrating speed to 200r/min, the amplitude to 20mm, and take it out after vibrating for 120min.
在本实施例中，210Po和210Bi在镍箔上自沉积回收率分别为99.3%和99.2%。In this example, the self-deposition recoveries of 210 Po and 210 Bi on nickel foil are 99.3% and 99.2%, respectively.
图1～图9分别为总氯离子浓度、不同温度下自沉积时间、制源溶液体积、振速和还原剂用量对210Po和210Bi在镍箔上自沉积回收率的影响。Figures 1 to 9 respectively show the effects of total chloride ion concentration, auto-deposition time at different temperatures, source solution volume, vibration velocity, and reducing agent dosage on the auto-deposition recovery of 210 Po and 210 Bi on nickel foil.
由图1可见，盐酸浓度为0.1mol/L时，总氯离子浓度在2.9～3.4mol/L时，210Po和210Bi的回收率稳定，可接近100%；由图2和图3可见，85℃以上制源60min，210Po和210Bi的同步峰值自沉积回收率接近100%，在制源60～120min时间段内，已经沉积的二核素不脱落；由图4和图5可知，在制源溶液20～30mL时，制源60min以上，210Po和210Bi的同步峰值自沉积回收率接近100%；由图6和图7可知，制源振速在140～200r/min之间，210Po和210Bi二核素均可在镍箔上同步达到接近100%的自沉积回收；由图8和图9可知，抗坏血酸加入量小于1g时，抗坏血酸本身及其氧化（脱氢）、水解产物未对210Po和210Bi在镍箔上定量自沉积产生影响，样品中TFe2O3含量一般低于15%，按称样量1.0g计算，0.3g抗坏血酸即能将制源溶液中的全部Fe3+离子还原。考虑到其他高价离子的存在，一般情况下向制源溶液中加入0.4～1.0g抗坏血酸。As can be seen from Figure 1, when the concentration of hydrochloric acid is 0.1mol/L, when the total chloride ion concentration is 2.9～3.4mol/L, the recoveries of 210 Po and 210 Bi are stable and can be close to 100%; as can be seen from Figure 2 and Figure 3, When the source is prepared above 85°C for 60 minutes, the simultaneous peak self-deposition recovery rate of 210 Po and 210 Bi is close to 100%. During the period of 60-120 minutes of source preparation, the deposited dinuclides do not fall off; as shown in Figure 4 and Figure 5, When the source solution is 20-30mL and the source is prepared for more than 60 minutes, the simultaneous peak self-deposition recovery rate of 210 Po and 210 Bi is close to 100%. It can be seen from Figure 6 and Figure 7 that the source vibration speed is between 140-200r/min , 210 Po and 210 Bi dinuclides can simultaneously achieve close to 100% self-deposition recovery on nickel foil; it can be seen from Figure 8 and Figure 9 that when the amount of ascorbic acid added is less than 1g, ascorbic acid itself and its oxidation (dehydrogenation), The hydrolyzate has no effect on the quantitative self-deposition of 210 Po and 210 Bi on nickel foil, and the content of TFe 2 O 3 in the sample is generally lower than 15%. According to the calculation of 1.0g sample weight, 0.3g ascorbic acid can make the source solution All Fe 3+ ions are reduced. Considering the existence of other high-valent ions, generally 0.4-1.0 g of ascorbic acid is added to the source solution.
本发明所给出的实施例仅是对本发明所提供的一种镍箔自沉积制源方法的举例，并不能涵盖全部发明内容；对本发明进行的替换与修改均应属于本发明所要求的保护范围。The embodiment provided by the present invention is only an example of a kind of nickel foil self-deposition source method provided by the present invention, and can not cover all the content of the invention; the replacement and modification of the present invention should belong to the protection required by the present invention scope.
