A comparison was made of the adsorption properties towards o-phthalic acid of ND100 resin modified by oxygen groups and ND900 resin modified by amine groups. The work presented focused on various properties including adsorption under static equilibrium conditions, the adsorption thermodynamics and kinetics. In addition, a method was devised for the separation of o-phthalic acid from maleic acid and fumaric acid in wastewater. Two isotherm models (Langmuir and Freundlich) were used to fit the static adsorption results. Both equations fitted the experimental data perfectly. The kinetic results led to the conclusion that the adsorption of o-phthalic acid onto ND900 involved a type of chemical transition.

Summary1. The presence of citrate in the normal fibrin enhanced the fibrinolytic activity of plasminogen activators, including trypsin. The effect of proteases (on normal or on heated fibrin, containing citrate) was not significantly influenced.2. The effect of plasminogen activators was also increased when excess of plasminogen was present in the normal fibrin plates.3. Fumaric acid and maleic acid belong to the polycarboxylic acids producing an enhancing effect.
