Procedure

A solution of dithizone, (diphenylthiocarbazone, C6H5NHNHCSN.NC6H5) was prepared by dissolving 0.025 gr. dithizone in 50 ml of di-isobutyl phthalate. Washed urethane foam cubes (prepared or described above) were impregnated by placing 1.0g cubes and 3ml of dithizone solution in a plastic bag and kneading until a uniform color developed on the cube. Excess solution was removed by blotting with sheets of whatman filter paper to give a finished cube of bright green color.
