Determination of total strontium in Uruguayan rice by inductively coupled plasma optical emission spectrometry (ICP-OES)

摘要

Strontium (Sr) is found naturally as a non-radioactive element and has 16 known isotopes. Naturally occurring Sr is found as four stable isotopes: Sr-84, -86, -87, and -88. Twelve other isotopes are radioactive. Sr-90 is the most important radioactive isotope in the environment, discovered mostly after the nuclear experiments conducted in the 1950s and 1960s.
