| Summary: | In this research, the application of chemical dissolution for removal of sediment covering ceramic of underwater archaeology has been studied. The first step of this research was analyses and identification the content of sediment covering ceramic of underwater archaeology using IR spectrophotometer, X-Ray Diffraction, and Atomic Absorption spectrophotometer. The second step was dissolution process of the sediment using Water, Na2EDTA, and H2O2 solution. In this step, the influences of dissolution time using water and concentration of the Na2EDTA and H2O2 solution have been evaluated.
The result of the study shows that the sediment covering ceramic of underwater archaeology contains of organic compound, soluble salt of Na and K, and insoluble salt of Ca, Mg, and Fe. Increasing the dissolution time in water solution has considenably increased the dissolution of the Na and K from sediment. Increasing of concentration Na2EDTA gives an increase in the Ca, Mg, and Fe dissolution from the sediment. The optimum concentration of H2O2 solution for dissolving organic compound is 30%. |
