毒理性

• 人类毒性摘录

锶的无机盐，如氯化锶、硫酸锶、碳酸锶等，都非常温和。在大量口服时，它们可能产生局部渗透压效应，因此倾向于引起呕吐和腹泻。

... Inorganic salts of strontium /such/ as the chloride, sulfate, carbonate ... are remarkably benign. ... In large oral doses they presumably exert local osmotic effects & so tend to induce vomiting & diarrhea.

这项研究调查了碳酸锶对Wistar品系大鼠骨骼畸形的影响，并使用骨骼制备（道森法和诺瓦克法）进行研究。同时，对有明显先天性脊柱侧弯的胎儿进行了组织学检查。在怀孕期间，将碳酸锶（200毫克/100克体重）与颗粒饲料（东方高望株式会社15克/天）或常规饮食混合后给予。结果显示，胸腰椎交界处出现了脊柱后凸，其他部位有时也显示出椎骨排列不齐。弯曲的脊椎骨体呈梯形。常规饮食组的骨骼畸形比颗粒饲料组更频繁且更明显。

THE SKELETAL MALFORMATIONS INDUCED IN RATS OF WISTAR STRAIN BY STRONTIUM CARBONATE WERE STUDIED WITH SKELETAL PREPARATIONS (DAWSON'S & NOVAK'S METHODS) & FETUSES WITH MARKED CONGENITAL KYPHOSIS WERE EXAMINED HISTOLOGICALLY. STRONTIUM CARBONATE (200 MG/100 G BODY WT) MIXED WITH A PELLET (ORIENTAL KOBO LTD 15 G/DAY) OR A ROUTINE DIET WAS ADMINISTERED DURING PREGNANCY. THE VERTEBRAL COLUMN SHOWED KYPHOSIS AROUND THE JUNCTION OF THORACIC & LUMBAR VERTEBRAE, & DISARRANGEMENT OF VERTEBRAE WERE SOMETIMES SHOWN AT THE OTHER PARTS. THE VERTEBRAL BODY AT THE CURVED VERTEBRAL COLUMN WAS TRAPEZOID IN FIGURE. SKELETAL MALFORMATIONS OF A ROUTINE DIET GROUP WERE MORE FREQUENT & MORE MARKED THAN A PELLET GROUP.

制备方法与用途

天青石复分解法：

1. 将粉碎后的天青石与纯碱溶液反应，温度控制在100℃。
2. 碳酸钠初始浓度为20%，加入量为理论量的110%，矿粉粒度需达到80目。在此条件下，分解率可达97%以上。
3. 过滤后，滤液中硫酸钠浓度可高达24%。使用水打浆法处理粗制碳酸锶，并加盐酸调整pH值至3，在90-100℃下反应2-3小时。
4. 加入除钡剂去除杂质，再用氨水调整pH值至6.8-7.2进一步除去杂质。过滤后滤液用碳酸氢铵或碳酸铵溶液沉淀出碳酸锶，经过滤去除氯化铵溶液，干燥滤饼制得成品。

反应方程式：

• SrSO₄+Na₂CO₃→SrCO₃+Na₂SO₄
• SrCO₃+2HCl→SrCl₂+CO₂↑+H₂O
• SrCl₂+NH₄HCO₃→SrCO₃+NH₄Cl+HCl

煤还原法：

2. 将粉碎后的天青石与煤粉按1：0.6-1：0.7的比例混合，在1100-1200℃温度下还原焙烧，时间为0.5-1小时。
3. 经过两次浸取和一次水洗。浸取温度为90℃，每次浸泡3小时，总浸出率可达82%以上。
4. 滤液经过滤处理后，滤渣用盐酸进一步回收锶。滤液中加入芒硝溶液去除钡离子，再添加碳酸氢铵或碳酸钠生成碳酸锶沉淀。经过分离、干燥和粉碎制得成品。

反应方程式：

• SrSO₄+2C→SrS+2CO₂
• 2SrS十2H₂O→Sr(OH)₂+Sr(HS)₂

菱锶矿热解法：

4. 将菱锶矿和焦炭粉碎，按重量比10：1的比例混合，并在1150-1250℃下焙烧。
5. 熟料经过三级浸取。二级和三级可在70-80℃下进行。最适浸取温度为95℃，有利于Ca²⁺、Mg²⁺杂质的分离。
6. 向滤液中加入碳酸氢铵进行碳化生成碳酸锶沉淀，并经过分离、烘干和粉碎制得成品。

反应方程式：

• SrCO₃→SrO+CO₂↑
• SrO+H₂O→Sr(OH)₂
• Sr(OH)₂+NH₄HCO₃→SrCO₃↓+NH₃·H₂O+H₂O

综合利用法：

• 将粉碎后的天青石与纯碱溶液反应，温度控制在100℃。
• 过滤后滤液中硫酸钠浓度可高达24%。使用水打浆法处理粗制碳酸锶，并加盐酸调整pH值至3，在90-100℃下反应2-3小时。
• 加入除钡剂去除杂质，再用氨水调整pH值至6.8-7.2进一步除去杂质。过滤后滤液用碳酸氢铵或碳酸铵溶液沉淀出碳酸锶，经过滤去除氯化铵溶液，干燥滤饼制得成品。
