Here, multiwall carbon nanotubes decorated with NiFe2O4 nanoparticles were synthesized
by 9 a simple reaction. Then, the nanoparticle was modified with 3-(trimethoxysilyl)-1-10
propanthiol. The modified-multiwall carbon nanotubes decorated with NiFe2O4
nanoparticles 11 were applied as a solid-phase extraction (SPE) sorbents to extract ultra
trace amounts of 12 Pb (II) from water samples. Detection in this technique was performed
by flame atomic 13 absorption spectrometry. The influences of effective parameters affect ...
