1.	Which method of refining will you suggest for an element in which impurities present have chemical properties close to the properties of that elements?
Answer» the statioary phase is selected in such a way that the impurities are more stongly adsorbed or are more soluble In the stationaary phase than component to be purified thus ,when the column is extracted , the impurities will be retained by the statioary phase while the pure component is easily eluted.
