作者对磷酸氢钙、硫酸铝钾、氢氧化钙和骨碳的除水氟效果、速度以及除氟后水中钙磷含量进行了比较。含氟水中的原始氟浓度为０．５３ｍｍｏｌ／Ｌ。每１００ｍｌ含氟水中加入８０ｍｇ的十二水硫酸铝钾在１ｈ内可将氟浓度降至正常水平（０．０６ｍｍｏｌ／Ｌ）；每１００ｍｌ含氟水中加入２００ｍｇ的磷酸氢钙需１２ｈ将水氟浓度降至正常水平，氢氧化钙和骨碳单独作用的效果较差。使用除水氟剂后．水中钙、磷浓度和ｐＨ值符合《生活饮用水卫生标准》。 The authors compared the effect of fluoride removal, the speed of calcium phosphate dibasic, potassium aluminum sulfate, calcium hydroxide and bone carbon in water and the calcium and phosphorus content of water after fluoride removal. The original fluorine concentration in the fluorine-containing water was 0.53 mmol / L. Per 100ml of fluorine-containing water by adding 80mg of aluminum sulfate dodecahydrate within 1h fluorine concentration can be reduced to normal levels (0.06mmol / L); per 100ml of water containing 200mg of calcium hydrogen phosphate to be 12h water fluoride concentration Down to normal levels, calcium hydroxide and bone carbon alone less effective. After using water fluoride agent. Water calcium, phosphorus and pH values ​​in line with “drinking water health standards.”
