Surface plasmon resonance sensor for detecting of arsenic in aqueous solution using polypyrrole-chitosan-cobalt ferrite nanoparticles composite layer
文摘
m" id="list_li0005">

A PPy-Chi/CoFe2O4 nanoparticle composite layer was prepared using an electrodeposition method

The composite layer was used to detect the arsenic in water, and the sensor limitation was about 0.001 ppm.

The composite layer was tested using atomic-force microscopy before and after the detection of arsenic.

The PPy-Chi/CoFe2O4 nanoparticle composite layer had adsorbed the As(V) in aqueous solution.
