Modeling of Ion-exclusion and Vacancy Ion-exclusion Chromatography on a Strongly Acidic Cation-exchange Resin in the H+ Form
Ion-exclusion chromatography (IEC) can sometimes be used for separation of the weak acids using pure water as mobile phase. Characteristic leading (i.e. frontally tailing) peaks are obtained and retention depends on the concentration of solutes. It was recently shown that this order could be reversed. In vacant ion exclusion chromatography (vIEC) sample flows as mobile phase and pure water is i...
متن کاملBiocompatibility research of a novel pH sensitive ion exchange resin microsphere
The main objective of this study was to investigate biocompatibility and provide in vivo pharmacological and toxicological evidence for further investigation of the possibility of pH sensitive ion exchange resin microsphere for clinical utilizations. Acute toxicity study and general pharmacological studies were conducted on the pH sensitive ion exchange resin microsphere we prepared. The genera...

متن کاملThe agglutination of ion exchange resin particles coated with polysaccharide.
NH20H + DPN2H -* NH40H + DPN. If NH4OH is used as substrate and the pH maintained above neutrality, the reverse reaction can be demonstrated (figure 1). In the absence of substrate, extract, or coenzyme no decrease in transmission was noted. NH4C1 and (NH4)2S04 were inactive as substrates at pH 7.0. The enzyme is stable at 60 C for 5 minutes, but not at 65 C. No loss of activity was noted after...
متن کاملDynamic Drying of Benzene with Ion-exchange Resin
Various organic solutions are used in many industries such as the petrochemical industry. The presence of moisture in those solvents results in poor insulation, corrosion of apparatus and catalyst poisoning. Therefore, the moisture content of the solvents must be reduced to less than several ppm. Since ion exchange resins have an ability to adsorb selectively polar substances fromnonpolar solve...
