The operation of filtering of a small amount of precipitate, washing of the precipitate, dissolving it in solvent and estimating it by volumetric or colorimetric method is very often used. However, the quantitative treatment of a small amount of precipitate is no easy problem and many difficulties are accompanied with this operation. The writer devised a simple filtering apparatus by application of a filter stick and a very rapid operation could be carried out. With the use of this apparatus, a semimicro quantitative estimation of aluminum and magnesium(10.05mg)by oxine is investigated and a suitable condition for formation of precipitate is determined.
