Inhalation: May cause respiratory tract irritation. Chronic: Chronic ingestion of iodides during pregnancy has resulted in fetal death, severe goiter, and cretinoid appearance of the newborn.. Prolonged exposure to iodides may produce iodism in sensitive individuals. Symptoms could include skin rash, running nose and headache. May cause kidney damage. Section 4 - FIRST AID MEASURES Eyes: Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid. Skin: Get medical aid. Flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse. Ingestion: Never give anything by mouth to an unconscious person.

制备

主要通过碳酸铷与纯氢碘酸反应或Rb2SO4和相当量Ba(OH)2作用，再用HI中和生成的RbOH，至无碱性反应。

为了得到碳酸铷纯品，将纯RbCl加过量草酸，在铂皿中强热，转变成碳酸盐。将此残渣溶于HI中，蒸发溶液至干，熔体应不显碱性。
