| It is well known that most of the defluoridation techniques involve the use of aluminum compounds because of the similarities of the charges of the fluoride ions with that of hydroxyl ions and the ease of replacement of the fluoride ions with that of hydroxyl ions to form fluoride aluminum hydroxide complex.¿´Ò»ÆªÎÄÏ׺ó¤µÄÒ»¾ä»°£¬Ô½¿´Ô½±ðŤ£¬Äܲ»ÄܰïÎÒÓÃÁ½¾ä»°±í´ïÏàͬÒâ˼¡£ÏÈллÁË |
