In this study, thiosemicarbazide bearing chitosan and their metal complexes have been
synthesized successfully. Next, all complexes were analysed by using Infrared
spectroscopy (IR), Ultraviolet-visible spectroscopy (UV-Vis), CHNS element analyser,
and Electrical impendence spectroscopy (EIS). The data analysis of the infrared
spectrum for ligand showed the important band for the functional groups of v(C=S),
v(C=N), v(C=O), and v(N-H) with the frequencies observed in 1165.50cm -1 ,
1621.27cm -1 , 1645.57cm -1 , and 3370.27cm -1 respectively. UV-Vis spectrum for ligand
has its own band that is show two peaks of absorption which are at 237nm is for π →
π ∗ transition for C=C benzene ring and at 321nm is transition of n → π ∗ for two main
chromofor (C=N) and (C=S). This analysis is further strengthened when the data from
the CHNSO element analyser exhibit the reading value below 5% for each element.
Lastly, by using EIS it is show that complexes containing zinc ion has higher
conductivity value 2.33x10 -6 Scm -1 .
