Interaction of Cu(II) with cellulose pulp was studied by means of polarography, AAS, and ultraviolet-visible spectrophotometry. The experiments were carried out at room temperature and at selected initial cellulose pulp slurry pH values between 7.0 and 13.0.The results obtained showed a trend of decreasing pH after chemical degradation of the pulp (2% w/w) as well as after further addition of a Cu(II)...
Amylose fractions of different peak Degree of Polymerisation (DP) (DP20, DP60, DP400, DP950) were complexed with docosanoic acid (C22) and glyceryl monostearate (GMS) at 60 and 90 °C. Complexation yields, relative crystallinities, dissociation temperatures and enthalpies increased with amylose chain lengths (DP20–DP60–DP400). Relative crystallinities and thermal stabilities of the DP950-complexes...
