Sodium chloride mineral water solution is of good quality in Sanshui county. But sulphate ion content in the solution is so high that it has an unfavourable influence over the industry where chlorine and caustic soda are produced. 三水县矿盐水是一种优质的食盐水溶液,但其中SO4~(2-)的含量较高,对氯碱工业有不良的影响。
Chlorine as a main component in groundwater is hard to form soluble minerals which is also hardly adsorbed by the clay mineral and accumulated by creatures. Because of this features, chlorine can transport free in groundwater. 氯作为地下水中的宏量组分普遍存在于地下水中,其不形成难溶矿物,不被粘土矿物所吸附且不能被生物积累,可以在水中自由的迁移。
