SEPARATION/PRECONCENTRATION AND DETERMINATION OF TRACE AMOUNTS OF PALLADIUM USING MODIFIED ALUMINA COATED MAGNETITE NANOPARTICLES WITHOUT CHELATING AGENT

In the present article, a simple, rapid, selective, sensitive and economical method has been developed for the separation/preconcentration of the trace amounts of Pd(II) in different real samples using alumina coated magnetite nanoparticles modified by sodium dodecyl sulfate and its determination by...
