改性海泡石除氟影响因素分析及机理探讨

对海泡石除氟条件及机理进行了实验探讨。结果表明,海泡石经过活化改性后,具有降低水中氟离子含量的作用。活化海泡石与含氟溶液的作用时间、海泡石用量、水中氟离子沈度以及酸度等因素都会影响除氟效果。活化海泡石除氟机理是由于活化过程,靠离子交换作用吸附了一定量的铝离子,而铝离子又与水中的氟离子结合从而达到除氟目的。

Study on action and mechanism of removing fluoride with activated meerschaum

The conditions and mechanism of removing fluoride ions from water by activated meerschaum have been investigated in this paper.Some major factors that effecting the treating process such as treating time and pH,concentration of fluoride ions,amount of meerschaum are studied.The experimental results show that activated meerschaum has an ability of removing fluoride due to the ion exchange and adsorption.
