嫩江位于松花江上源,是松花江水系的主要支流,也是我国北方黑龙江省的主要地表水源。研究其天然水中元素自然背景值和赋存状态,可为研究水质变化规律和元素的迁移转化提供重要的科学依据。本工作用中子活化分析法测定了嫩江上游河水、沼泽水、湖水和雨水中25种元素的自然背景值和20种元素的赋存状态。
Nenjiang River is located in the Songhua River source, is the main tributaries of the Songhua River system, but also in northern China’s Heilongjiang Province, the main surface water. Studying natural background values and occurrences of elements in natural water can provide important scientific evidences for studying the regularity of water quality and the migration and transformation of elements. In this work, the natural background values of twenty-five elements in the river, swamp water, lake water and rainwater in the upper Nenjiang River were determined by neutron activation analysis and the occurrence state of twenty elements.
