File:Paper Chromatography-Separation of mixtures of ions (Pb2+ & Ag+) by Paper Chromatographic Technique pp 229-231.pdf

Paper chromatography (PC) is a simple technique to separate mixtures of metal ions, amino acids, sugars, dyes, and drugs. A very small amount of sample is required for the analysis. PC has also become a popular technique for the separation of metal cations (basic radicals). In this experiment, the use of PC will be illustrated to separate a mixture of cations (group I and group II in the analytical table) and also identification of the unknown metal ion with the help of their Rf values and colour zones of cations. Compare the Rf values and also colour zones of individual cations with that of their Rf values in the known mixture and in unknown.
