Research
conducted is related to the preparation and characterization of dithizone
method based on extraction of cadmium, lead and zinc trace metals from seawater
samples. Inorganic metals or ions can act back with dithizone to produce
colourful coordination. The dithizone reagent is highly sensitive to the
presence of heavy metals such as plumbum (Pb), cadmium (Cd) and zinc (Zn) as
designated in this study. Inorganic metals or ionic can react with dithizone to
produce colored coordination compounds. The resulting dithizoneate may be
extracted with an organic solvent such as carbon tetrachloride (CCl₄).
This study also involves steps such as adjusting the pH value in order to
produce the dithizoneate metal product we need. In this study, metal powders
were dissolved in seawater samples and extracted with dithizone to enhance the
detection and extraction facilities. We analyze trace metals carried out by
plasma atomic emission spectroscopy (ICP-OES) to see the efficiency of
dithizone extraction methods into seawater samples used. Dithizone extraction method used in extracting Pb element indicates a good
performance.
