In the extraction , strontium was in aqua phase with the presence of tetraphenylborate as the counter anion, while organic phase (1- octanol was chosen) was complexed with 4'.4"(5")-di-(tert-butylcyclohexano)-lS-crown-6 (7:1 respectively ). Strontium from the organic phase was Mechanism of vortex assisted liquid liquid microextraction of strontium in water sample stripped with nitric acid back to aqueous solution and determined by ion chromatography.
