Abstract

Abstract

Radiochemical analysis auto-system of ⁹⁰Sr in liquid effluent from nuclear facilities was developed by using solid phase extraction disk to absorb Sr, Geiger counter to measure the activity of ⁹⁰Sr, solenoid valves and programmable controllers and so on. The system realizes the automation of sampling, enrichment, purification and activity measurement. The analysis time is about 30 min and the detection limit is less than 1 Bq/L, which can meet the requirement of ⁹⁰Sr analysis in liquid effluent from nuclear facilities.
- ⁹⁰Sr,
- solid phase extraction disk,
- automatic analyzer
