Abstract Adsorption of radium‐226 on quartz is investigated. Adsorption isotherms are obtained for crystalline and sulphuric and hydrochloric acid‐treated quartz samples at pH 1 and 10. Desorption of radium‐226 from silica with EDTA and an EDTA‐KC1 mixture is also studied. It is found that radium‐226 adsorbed on silica is difficult to desorb whereas radium deposited on silica as radium sulphate is easily removed in EDTA solutions.
