地下水在岩土空隙内渗流的过程中,水与岩石之间会发生多种不同的化学作用,使地壳内一些矿物元素和气体进入水中。这样,水中就会含有某些有用的化学组分和气体组分或微量元素,遂形成人们通常所称的“矿泉水”。矿泉水最重要的特征就是含有大量的矿物质和游离二氧化碳。一般组成天然矿泉水成分的元素可分为4组:第1组是水中溶解的常量元素,一般包括钾、钠、钙、镁、铁、铝、氯、硫、氮、氢、氧、碳、硅等;第2组是含量不大的元素,有溴、锶、铷、铅、镍、锌、锰、
During the seepage of groundwater in the rock and soil voids, a variety of chemical interactions occur between the water and the rock, causing some of the mineral elements and gases in the crust to enter the water. In this way, the water will contain some useful chemical components and gas components or trace elements, thus forming the so-called “mineral water.” Mineral water is the most important feature contains a lot of minerals and free carbon dioxide. The general composition of natural mineral water elements can be divided into four groups: the first group is a dissolved element in water, generally including potassium, sodium, calcium, magnesium, iron, aluminum, chlorine, sulfur, nitrogen, hydrogen, oxygen, Silicon, etc .; Group 2 is a small amount of elements, bromine, strontium, rubidium, lead, nickel, zinc, manganese,
