/HUMAN EXPOSURE STUDIES/ ... A group of 11 healthy young adults volunteered to participate after verbal and written information and consent. After a 1-week fluoride depletion period, the subjects consumed popcorn prepared with either fluoridated (250 mg/kg) or non-fluoridated salt during 30 minutes. Unstimulated whole saliva and samples of supragingival plaque were collected before consumption (baseline) and at 30, 60 and 120 minutes after the intake. Fluoride concentration was determined with a fluoride-specific electrode and the post-ingestion levels were compared with baseline by ANOVA. ... In saliva, the mean fluoride concentrations at baseline ranged from 0.021 to 0.027 mg/L and after the 30 minutes consumption of fluoride prepared snacks a 15-fold increase (p<0.001) was found. The same pattern was disclosed in the plaque samples. In both saliva and plaque, the fluoride levels remained significantly elevated after 2 hours (p<0.001 and p<0.05, respectively). /The authors concluded that/ consumption of snacks prepared with fluoridated table salt resulted in significantly increased fluoride levels in saliva and supragingival plaque for a period of at least two hours. /Fluoride/

/SURVEILLANCE/ Acute fluoride poisoning produces a clinical syndrome characterized by nausea, vomiting, diarrhea, abdominal pain, and paresthesias. In May 1992, excess fluoride in one of two public water systems serving a village in Alaska caused an outbreak of acute fluoride poisoning. /The authors/ surveyed residents, measured their urinary fluoride concentrations, and analyzed their serum-chemistry profiles. A case of fluoride poisoning was defined as an illness consisting of nausea, vomiting, diarrhea, abdominal pain, or numbness or tingling of the face or extremities that began between May 21 and 23. ... Among 47 residents studied who drank water obtained on May 21, 22, or 23 from the implicated well, 43 (91 percent) had an illness that met the case definition, as compared with only 6 of 21 residents (29 percent) who drank water obtained from the implicated well at other times and 2 of 94 residents (2 percent) served by the other water system. /The authors/ estimated that 296 people were poisoned; 1 person died. Four to five days after the outbreak, 10 of the 25 case patients who were tested, but none of the 15 control subjects, had elevated urinary fluoride concentrations. The case patients had elevated serum fluoride concentrations and other abnormalities consistent with fluoride poisoning, such as elevated serum lactate dehydrogenase and aspartate aminotransferase concentrations.

这项研究旨在量化比较年轻成年狗、猫、兔、大鼠和仓鼠化物短期药代动力学的主要特征——即血浆(Cp)、肾脏(Cr)和非肾脏(Cer)清除率。在静脉注射化物(0.5 mg F/kg)后七小时内收集血浆和尿液样本。狗和仓鼠的Cp分别为3.5至8.6 mL/min/kg。Cr在狗和兔中小于1.5 mL/min/kg,在大鼠和仓鼠中约为3.5 mL/min/kg。Cer在狗中为2.1 mL/min/kg,在猫、兔和仓鼠中超过4.5 mL/min/kg。研究结论是:(1)这五种物种在化物的代谢处理上存在显著的定量差异;(2)年轻成年狗的Cp、Cr和Cer值,经过体重校正后,与年轻成年人类最为接近。/化物/
This study was designed to quantitate and compare the major features of the short-term pharmacokinetics of fluoride--i.e., the plasma (Cp), renal (Cr), and extra-renal (Cer) clearances--in young adult dogs, cats, rabbits, rats, and hamsters. Plasma and urine samples were collected for seven h after the iv administration of fluoride (0.5 mg F/kg). Cp ranged from 3.5 to 8.6 mL/min/kg in the dog and hamster, respectively. Cr ranged from less than 1.5 mL/min/kg in the dog and rabbit to about 3.5 mL/min/kg in the rat and hamster. Cer ranged from 2.1 mL/min/kg in the dog to over 4.5 mL/min/kg in the cat, rabbit, and hamster. It was concluded that (1) there are major quantitative differences in the metabolic handling of fluoride among the five species, and that (2) Cp, Cr, and Cer values of the young adult dog, when factored for body weight, resemble those of the young adult human most closely. /Fluoride/

吸收、分配和排泄
本综述的目的是介绍化物代谢的一般特征,特别是当通过含盐摄入时。摄入的含盐中的化物在胃和小肠吸收后,其代谢过程与溶性化物或其他含有离子化化物的载体的代谢过程相同。然而,由于含盐几乎总是与食物一起摄入,因此从胃肠道的吸收可能会延迟或减少。处理此主题的报告表明,化物的吸收被延迟,因此,峰值血浆浓度低于与一起摄入化物时的浓度。然而,最终被吸收的摄入化物量并未显著受到影响,除非膳食主要由高浓度的成分组成。在这种情况下,吸收程度可以减少多达50%。含盐的摄入频率也比含低。数据显示,摄入剂量和频率对体内化物的保留、血浆、骨骼和牙釉质中的浓度仅有轻微影响。最后,计算结果表明,从含盐中急性中毒的风险几乎不存在。
The purpose of this review is to present the general characteristics of the metabolism of fluoride particularly as it occurs when ingested with fluoridated salt. Following the absorption of salt-borne fluoride from the stomach and intestines, its metabolism is identical to that of water-borne fluoride or other vehicles containing ionized fluoride. Because fluoridated salt is almost always ingested with food, however, absorption from the gastrointestinal tract may be delayed or reduced. Reports dealing with this subject have shown that fluoride absorption is delayed and, therefore, peak plasma concentrations are lower than when fluoride is ingested with water. The amount of ingested fluoride that is finally absorbed, however, is not appreciably affected unless the meal is composed mainly of components with high calcium concentrations. In this case, the extent of absorption can be reduced by as much as 50%. Fluoridated salt is also ingested less frequently than fluoridated water. Data are presented to show that the dose size and frequency of ingestion have only minor effects on fluoride retention in the body and on the concentrations in plasma, bone and enamel. Finally, calculations are presented to show that the risk of acute toxicity from fluoridated salt is virtually non-existent. /Fluoride/

制备方法与用途

氟化钾是一种盐,又叫钾的氟化盐,其为白色单斜结晶或结晶性粉末,味咸,易吸湿,溶于水而不溶于乙醇。其水溶液呈碱性,能腐蚀玻璃和瓷器,因此通常可用作各种玻璃刻蚀、焊接助熔剂、木材防腐剂,农业杀虫剂、农药中间体、制药工业原料以及有机氟化原料,在建筑、化工业、农业具有不可或缺的作用。氟化钾还是最常用的氟化剂之一,可以说没有氟化钾就没有蓬勃发展的氟化工。而氟化钾作为氟化剂最重要的时期反应活性,作为氟化剂,特别是在精细化工的生产与应用中,高活性氟化钾有普通无水氟化钾无可比拟的优势。氟化钾是生产氟化物的基础原料,化学式KF。分子量58.10。无色立方晶体或白色粉末。有毒!易潮解。味咸。比重2.48。熔点858℃。沸点1505℃。易溶于水。 溶于氢氟酸及液氨。不溶于乙醇、丙酮。 水溶液呈碱性,能腐蚀玻璃及瓷器。对人体皮肤、粘膜、眼睛有刺激性。低于40.2℃时,在水溶液中结晶,得到二水合物KF·2H2O,后者为单斜晶体,41℃时可自溶于结晶水中。由氟化氢钾热分解或以碳酸钾(或氢氧化钾)中和氢氟酸(40% 或无水)而得。用于玻璃雕刻、食物防腐,也可用作焊接助熔剂、氟化剂、杀虫剂等。
氟化钾 分子结构式
图1为氟化钾分子结构式。氟化钠和氟化钾都是白色结晶,具有岩盐型结构。氟化钠在水中比较难溶(100℃、5g/100ml水),而氟化钾吸湿性强,在水中非常容易溶解(在18℃为 92.3g/100g水)。氟化钾有二水合物 (mp41℃) 及四水合物 (mp19.3℃)。
氟化钠和氟化钾与其他卤化碱金属盐(例如氯化钠)不同,它呈现碱性,容易和氟化氢发生加成反应生成酸式盐。
氟化钠和氟化钾可以分别用碳酸钠或碳酸钾,按计算量用氢氟酸中和就可以制成,若 氢氟酸过量时,就会带进来酸式盐 (酸式氟 化钠NaHF2或酸式氟化钾KHF2)。
K2CO3+2HF→2KF+H2O+CO2 KF+HF→KHF2。
氟化钠在工业上用氟硅酸钠和氢氧化钠水溶液反应进行制备。
Na2SiF6+6NaOH→6NaF+Na2SiO3+3H2O
氟化钠是价格最低廉的氟化碱金属,利用和氟化氢能生成酸式盐这一点,在原子能工业及其他方面作为氟化氢的吸附剂使用。
氟化钾和氟化钠相比,在各种溶剂中更易于离解。由于易于生成氟化物离子(F-)因此可以作为有机化合物的氟化剂,尤其是作为卤交换法用氟化试剂使用。
RCl+KF→RF+KCl
还有最近利用氟化物离子与氢离子的结合力强这一点,在有机反应中逐渐用氟化钾作缩合剂使用。氟化氢钾亦称“氟氢化钾”、“酸式氟化钾”、“重氟化钾”,是氢氟酸的酸式盐。化学式KHF2。分子量78.11。无色等轴晶系结晶,易潮解。有毒!相对密度2.369g/cm3。易溶于热水,溶于乙酸钾,不溶于无水乙醇。水溶液呈酸性,强烈腐蚀玻璃和陶瓷。受热至约225℃时分解。在潮湿空气中吸收水分放出氟化氢。
制法:将氢氧化钾或碳酸钾与足量的氢氟酸作用,或向饱和氟化钾溶液中加入氢氟酸,控制终点的pH为2~3而得。
用途:电解熔融的氟化氢钾可得到氟。工业上用于制氟及氟化物,雕刻玻璃,也用作掩蔽剂、冶金助熔剂、防腐剂等。

142g/60℃;150g/80℃

1)将1000g氢氧化钾溶于800g水中得到氢氧化钾溶液,向氢氧化钾溶液中通入氟化氢气体,氟化氢气体的通入速率以保持反应温度在40-70℃为宜;

2)当反应液的PH值达6.8时,停止通入氟化氢气体,中和反应完成;

3)将反应液沉降静置12小时后,取上层清液;

4)将上清液冷却至21℃,加入1g氯化钙,氟化钾水溶液即在瞬间完成结晶;

5)抽滤并用饱和氟化钾水溶液洗涤后,将滤饼放入真空箱干燥4小时即得99.5%的高纯度氟化钾产品。
