A simple microwave-assisted synthesis of cobalt ferrite nanoparticles and its application for the determination of lead ions in rooibos (Aspalathus linearis) tea

•CoFe2O4 nanoparticles were used to preconcentrate Pb ions from rooibos tea samples.•Detection sensitivity of the FAAS system was enhanced by about 80 folds.•LOD and LOQ values of lead were calculated as 5.3 and 17.6 µg/L, respectively.•Recovery results were calculated in the range of 77–125% using...
