摘要
钾在自然界主要以硅酸盐、硫酸盐化合物和卤化物存在，在表生带具有较强的迁移能力，因此在地下水中分布较广。钾是人体中的必需元素，正常情况下需摄入３ｇ／ｄ，过量摄入钾或缺钾都可能导致疾病的发生。饮用水中的钾是人体所需钾的主要来源。因此，寻找和开发含钾量较高的地下水作为生活饮用水，将有利人群健康。
In nature, potassium is mainly present in silicate,sulfate,halide, and has a strong migration behaviour in supergene zone, so potassium is widely distributed in groundwater. Potassium is an essential element in human body. It is needed in a normal quantity of 3g/d,overmuch or lack of patassium in human body can lead to illness. Drinking water is a main resource of patassium. So investigating and developing underground drinking water which highly contains patassium will favourable to the health of people.
