EFFECT OF IONIC CROSSLINKING ON DENSITY OF HYDROGEL CHITOSAN MEMBRANES
Journal Title: Progress on Chemistry and Application of Chitin and its Derivatives - Year 2013, Vol 0, Issue
Abstract
Ionically crosslinked chitosan membranes were prepared and their density was determined using modified pycnometer method. High‑molecular compound: sodium alginate (NaAlg) and low‑molecular compounds: pentasodium tripolyphosphate (TPP) and trisodium citrate (CIT) were used as ionic crosslinkers of chitosan. As a reference liquid n-heptane solution was chosen. It was found out that density of modified chitosan membranes is strongly affected by the type of ionic crosslinker and membrane preparation conditions.
