PB Resin

Pb Resin is available in three particle sizes (100-150 mm, 50-100 mm, and 20-50 mm), in the bottle sizes shown below or prepackaged in slurry packed 2 mL columns and 2 mL dry pack cartridges. Contact us for availability of other column or cartridge sizes.

Pb Resin is an extraction chromatographic material based on the same crown ether extractant used in the Sr Resin. Pb Resin contains at a lower concentration of the crown ether dissolved in a longer chain alcohol diluent to facilitate the stripping of Pb from the resin. The retention of Pb is high (i.e., k’ > 100) across the range of nitric acid concentrations from 0.1M to 10M, and Pb can be eluted from the column using 6-9M HCl, 0.1M ammonium citrate, 0.05M ammonium acetate or other buffer solution. In some cases the elution of Pb from Pb Resin with deionized water may be possible. However, to ensure consistently high Pb recoveries, the use of a water eluent is not recommended.
