Structure and properties of commercial Chitosan-50 powder ((C6H11NO4)n, M=500.000, Wako Pure Chemical Industries Ltd.) were investigated. XRD, IR spectroscopy, DTGA and SEM were used. It was shown that chitosan powder is characterized only by chitosan phase and flaky flat irregular particles and agglomerates sized from 5 nm to 200 μm. Decomposition of chitosan is complete at 580 °C. Specific […]

Glassy carbon electrode (GCE) has been modified by mechanical entrapment method with Polyaniline Nanoparticles / Graphene for developing a new nanosensor (PANINPs/GR/GCE). It was characterized by electrochemical analysis to evaluate it as a nano-sensor for analytical electrochemistry. A standard solution of 0.06 mM K4[Fe(CN)6] in 0.1M KCl was used as an electrolyte, in order to […]
