摘要

为对生物样品中

Sr进行快速有效地检测和缩短检测周期，本研究采用新型Sr

#183;Spec固相萃取树脂对生物样品中

Sr进行分离纯化，结合硝酸消解预处理、碳酸盐沉淀、低本底α/β测量等，通过大量实验验证，建立了一种生物样品中

Sr的快速检测分析方法。该方法直接对

Sr进行富集分离和测量，省去

Sr与

Y平衡时间，检测周期大幅缩短，对Sr化学回收率约为80%。

Abstract

Background:

Sr is the key monitoring object in the domestic and foreign environment because of its high fission yield and long half-life. There are mainly three methods in current standards

which are all used to measure the content of

Y for calculating the content of

Sr. All these methods have long experimental periods.

Purpose:

This study aims to build a method to detect

Sr in biological samples rapidly and effectively and to shorten the detection period.

Methods:

A new

Sr detection method in biological samples is built. And a new Sr

#183;Spec solid phase extraction resin is used to separate and purify

Sr in this method

combined with digestion pretreatment

carbonate precipitation

low background alpha and beta measurement.

Results:

This method is to determine directly the content of

Sr. The detection period was shortened obviously and the recovery of Sr was about 80%.

Conclusion:

Experimental results show that the new method is rapid and effective for

Sr detection in biological samples.
