摘要
一、前言海洋环境中^(106)Ru的污染监测很重要。由于^(106)Ru在海洋环境中的价态和存在形式复杂,使分析很困难。国外理想方法不多。本文的201海水中^(106)Ru的分析流程有别于国外的有:CoS浓集量大3倍;还包含了除CoS的条件和除H_2SO_3的步骤等。海水中^(106)
This paper describes the analytical procedure of Ru-106 for marine environ-mental samples. The procedure includes sample pretreatment, CCl_4 extraction,mag-nesium powder reduction and β counting. The recovery is 88±5%. Minimumdetectable limit is n×10^(-3)Bq/1(g). It is a routine method which belong to 《TheStandard of Survey and Monitoring for Marine Pollution》
