Pu(IV) � Nitric Acid (cont)<br />
• The adsorption rate of Pu(IV) increases with<br />
increasing temperature.<br />
• In addition, the adsorption rate is significantly<br />
higher for resins with lower cross-linking.<br />
• Both of these factors also apply to the elution.<br />
• Temperatures about room temperature and less<br />
cross-linked resins are therefore often used.<br />
• Increased temperature may, however, promote<br />
Pu hydrolysis in very dilute eluents.<br />
