4 new compounds of bis-(carbonyl thiourea) derivatives were successfully synthesized
through a condensation reaction by carbonyl chloride derivatives, ammonium
thiocyanate and 2,2-ethylenedioxy bis(ethyl) amine. The main focus of this research
is to react bis-(carbonyl thiourea) with selective transition metal salts such as
copper(II), cobalt (II) and nickel(II) ions. All of these compounds were characterized
using Fourier-Transform Infrared (FT-IR), 1 H and 13 C Nuclear Magnetic Resonance
(NMR), CHNS Elemental Analysis and Ultraviolet- Visible Spectroscopy (UV-Vis). Para
methoxy and para methyl thiourea were tested for their absorptivities towards metal
salts such as copper(II), cobalt(II) and nickel(II) ions through analytical method which
was Atomic Absorption Spectroscopy(AAS). Both para methoxy and para methyl
thiourea showed around 15 percent absorption towards copper(II) and cobalt(II) ions
while nickel(II) ion showed the highest absorption by both thiourea which is around
30 percent.
