福建南部矿泉水化学

Chemistry of Spring in Southern Fujian

利用三角化学组份图解法,研究福建南部矿泉水化学,发现龙岩、永安地区矿泉水基本为Ca^(2+)—HCO_3^-型,而沿海地区水样受生?光风化产物的影响较显著,这反映出地质条件对水质的支配作用,根据水中溶解组份的不同来源,定量地估算出火成岩风化产物对矿泉水中HCO_3^-和K^+,Na^+等离子组分的贡献比例。

By using the ternary diagram of chemical composition to study the chemistry of spring water in the Southern Fujian,it has been found that the spring water, in Longying and Yungan area belongs to Ca2-HCO3-style, Whereas the water in coastal area are obviously affected by weathering products of silicates, reflecting the domination of water chemistry by geolo-gical conditions. According to different resouces of dissolved composition, the contribution ratios to HCO3- and Na++K+ in the spring water by weathering products of ignous rocks have been established.
