WebBuffer counterions should have the same charge as the resin; for negatively charged cation exchange resins, phosphate buffers are an excellent choice. Column equilibration. Equilibrate the column until pH and conductivity readings stabilize (typically requires 3–5 column volumes of buffer). WebThis result suggests that phosphate groups on the polymer have a higher affinity to the surface of nanoparticles. It is important to emphasize that the incomplete ligand exchange greatly influences the colloidal stability in aqueous media of final polymer coated UCNPs owing to the presence of hydrophobic oleic acid molecules.
