A Note on Inverse-Square Exchange Models

The su(1|1) symmetric version of the Haldane-Shastry spin chain is diagonalized by means of a linear transformation. The same transformation applied to the original su(2) model yields simple expressions for the Hamiltonian and the generators of the Yangian symmetry of the model in terms of spin wave operators. Several years ago Haldane and Shastry independently discovered a soluble spin chain w...

Competitive Ion Exchange Behavior on Oxides

Cation adsorption data using MnCl2 and the proton isotherm of a Si oxide were compared with pH as the variable. The cation adsorption data quantitatively correlated with the proton isotherm analysis; the H+/Mn* exchange ratio was 6.0. The presence of adsorption plateaus are due to pH-dependent (step) reactions; this was suggested as the only reasonable explanation for adsorption isotherms cover...

Displacement Chromatography on Synthetic Ion - exchange Resins

In Part 1 of this series of papers (Partridge & Westall, 1949) it was shown that, whilst the baseexchange resin Zeo Karb 215 may be used with success for the separation of the neutral and acidic amino-acids, certain difficulties arise when the separation of basic substances is attempted. These difficulties were traced to the phenolic hydroxyl groups of the resin. Resins of the sulphonated pheno...
