\nThe dye in black ink can be separated by the method of chromatography.
\n<\/section>\n
\nBlack ink is typically a mixture of several different coloured dyes. Chromatography is a technique used to separate components of a mixture based on their differential partitioning between a stationary phase and a mobile phase. Different dyes in the ink travel at different rates through the stationary phase (like paper), causing them to separate.
\n<\/section>\n
\nEvaporation is used to separate a soluble solid from a liquid. Fractional distillation separates liquids with different boiling points. Dialysis separates particles based on size using a semipermeable membrane. Chromatography is the standard method for separating different coloured dyes in ink.
