摘要

在放射性的环境总

监测中，为了确定泥土

核素的污染程度和对泥土环境质量作出评价，就要首先准确地测知其含钾量或预先从试样中将钾除去，但后者较麻烦。

Abstract

In this paper

a rapid and simple method for determination of potassium in soil is reported. It is high sensitive

less interfering with wide range of determination etc.

The content of potassium found by this method

can easily be used to estimate the quantity and

-radioactivity of

K. It offers the essential data for the measurement of total β-intensity (subtract the contribution of

K) in the monitoring of environmental radioactivity.

The recovery

include the treatment of the sample

is 98—105%

and the coefficient of variation (RSD) is 0.8%. The results given by three different methods (AAS

FS and TPB) are almost identical

the deviation is within 10%. It indicated that this method is dependable and applicable to routine analysis.

It can be used to determine potassium of other environmental samples.
