It is then reoxidized to the +3 state using hydrogen peroxide and then isolated by selective elution with 2 M hydrochloric acid (to remove impurities, including chromium) and finally 6 M hydrochloric acid (to remove the mendelevium). Source: Internet

It was found that lawrencium coextracted with the trivalent ions, but the short half-life of the 256 Lr isotope precluded a confirmation that it eluted ahead of Md 3+ in the elution sequence. Source: Internet

Mendelevium can finally be separated from the other trivalent actinides using selective elution from a cation-exchange resin column, the eluant being ammonia α-HIB. Source: Internet

The chromatographic separation behavior was then unknown for the element 97, but was anticipated by analogy with terbium (see elution curves). Source: Internet

However, if a direct "catcher" gold foil is used, the process is complicated by the need to separate out the gold using anion-exchange chromatography before isolating the nobelium by elution from chromatographic extraction columns using HDEHP. Source: Internet

Displacement chromatography has advantages over elution chromatography in that components are resolved into consecutive zones of pure substances rather than “peaks”. Source: Internet
