• Analysis of water soluble polymers using linear size exclusion HPLC columns and a semi-micro SEC system
  

  One of the most widely used water-soluble polymers is Polyvinylpyrrolidone (PVP). For more than 70 years it is applied in a variety of applications in medicine, pharmacy, cosmetics and industrial production. PVP binds to polar molecules exceptionally well. It supports the solubility of tablets in water, makes the glue stick adhesive and plays an essential role in the production of membranes. In ceramic, paper and dye applications, it produces visual effects such as gloss and brilliancy. As a food additive, PVP is a stabilizer (E1201). A characteristic feature of a certain polymer is its molecular weight distribution curve, which is usually obtained by SEC Analysis more

• Multi-walled carbon nanotubes — Solid phase extraction for isolating marine dissolved organic matter before characterization by size exclusion chromatography

  The feasibility of multi-walled carbon nanotubes (MWCNTs) for extracting dissolved organic matter (DOM) from seawater has been investigated. Solid phase extraction (SPE) operating in column and batch modes was used as an extractive technique, and the latter mode offered better performance. DOM adso more

• Complexation of Arsenite with Humic Acid in the Presence of Ferric Iron

  In the presence of iron (Fe), dissolved organic matter (DOM) may bind considerable amounts of arsenic (As), through formation of Fe-bridged As−Fe-DOM complexes and surface complexation of As on DOM-stabilized Fe-colloids (collectively referred to as As−Fe-DOM complexation). However, direct (e.g., ch more

  Our previous mechanistic discussion of the free‐radical crosslinking monoallyl/diallyl copolymerizations was extended to the cationic crosslinking monoepoxide/diepoxide copolymerizations, typically including 1,2‐epoxycyclohexane (ECH) as a monoepoxide and bis[3,4‐epoxycyclohexylmethyl] adipate (BECH more
