Application of silica gel 60 loaded with Aspergillus niger as a solid phase extractor for the separation/preconcentration of chromium(III), copper(II), zinc(II), and cadmium(II).


Sorption properties of silica gel 60 loaded with fungi cells characterized as Aspergillus niger were evaluated for trace enrichment of Cr(III), Cu(II), Zn(II), and Cd(II) from various water samples prior to the description of flame atomic absorption spectrometric analysis. The proposed SPE method is cheap, simple, highly sensitive, accurate, and selective… (More)
