摘要
目的 筛选良好的饮水除氟材料。方法 比较了 6种天然的和人工制造的吸附材料 (焦炭、煤矸石、骨碳、活性碳、活性氧化铝及羟基磷灰石 )对饮水中氟离子的吸附能力以及 p H值、投料量、吸附作用时间、再生方法、再生效果等因素对吸附除氟效果的影响。结果 发现上述 6种吸附剂均有一定的饮水除氟效果 ,其中羟基磷灰石对水中氟离子的吸附去除效果最好。结论 焦炭。
Objective To screen some good absorptive materials removing fluoride from drinking water. Methods Capacities absorbing fluoride, in drinking water, of six natural and man made absorbents ( coke, gangue, backbone, activated carbon, activated aluminum oxide, hydroxylapatite ) were compared. Effects of some factors (pH, quantity of absorbent, absorbing time, regenerating ways ) on removing fluoride from drinking water, were investigated.Results The above absorbents all have certain ability to absorb F - and remove fluoride from drinking water, and hydroxylapatite is the best among them.Conclusions Gangue coke, backbone carbon and hydroxylapatite are the better absorptive materials removing fluoride from drinking water.
