HEEP COPYRIGHT: BIOL ABS. In order to analyze metals in deposit rapidly, the ash of deposit was fused with NaOH and suspended with water. The mixture was filtrated and the filtrate was used for the estimation of Al, Si, V and Zn. The residue after filtration was dissolved with H2SO4 and Ti, Fe, Mn, Cu and Co were assayed from the solution. The measurement of metals in the filtrate or the H2SO4 solution was performed with colorimetry, titration and atomic absorption spectrometry. This complete analysis of the metals in de
