Pre-concentration and determination of 90 Sr in radioactive wastes using solid phase extraction techniques
S Dulanská, B Remenec, Ľ Mátel… - Journal of …, 2011 - akjournals.com
This paper describes the use of IBC′ s AnaLig® Sr-01 molecular recognition technology
product to effectively and selectively pre-concentrate, separate and recover strontium from
radioactive waste samples. The use and effectiveness of AnaLig® Sr-01 gel was
successfully validated by analysis of International Atomic Energy Agency (IAEA 375)
reference soil and National Physical Laboratory (NPL)–High Alpha–Beta (2003) liquid
sample. The second part of this paper focuses on analysis of radioactive waste samples …

Pre-concentration and determination of {sup 90} Sr in radioactive wastes using solid phase extraction techniques
S Dulanska, B Remenec, L Matel, D Galanda… - Bezpecnost Jaderne …, 2012 - osti.gov
Strontium 90 was determined in various samples by using the specific AnaLig Sr-01 sorbent
a gel Sr resin, combined with Cherenkov radiation measurement on a TRI CARB 2900TR
liquid scintillation spectrometer. The two methods were able to effectively determine {sup 90}
Sr in both liquid and solid samples. The accuracy and suitability of the method using AnaLig
Sr-01 was tested on 2 certified reference materials. No additional purification of the eluted
fraction was necessary. The advantages of the AnaLig Sr-01 sorbent as compared to Sr …
