Abstract
Interactions of sulfhydryl compounds and quinone derivatives with poly (4-vinylpyridine) gels have been studied. Adsorption of long-chain sul fhydryl compounds onto gels causes the gel to swell, whereas oxidation of the adsorbed sulfhydryl compound to disulfide by a quinone derivat ive results in the gel shrinking. The higher the donating ability of t he sulfhydryl compound, the stronger its interaction with a quinone de rivative and thus the faster the removal from the gels, as revealed by HPLC.
