Experimental study of albumin and lysozyme adsorption onto acrylic acid (AA) and 2-hydroxyethyl methacrylate (HEMA) surfaces

“…The NaCl concentration was in the range of 0.05-0.2 M [35]. The surfaces were placed in a phosphate buffer solution, pH 7.2 [36], similar to the pH of human tears [37], and kept for five days at 22 ± 0.1 • C. This period was required for the protein adsorption process to be completed and to reach an equilibrium state. Samples of solutions were taken and their absorbency was measured by UV-vis (M350 Double Beam) at 280 nm [38], which is the wavelength of the protein UVvis absorption.…”

The kinetics of the dissolution of chlorite as a function of pH and at 25°C

“…In addition to the reference standard, there are six primary standards to cover the pH range 3.5 to 10.3 and Vogel (1989) describes two operational standards to extend the range from 1.6 to 12.3. Bruno and Svoronos (1989) provide an extensive list of other possible buffer reagents. Some of the reagents contain strong complexing organic acids such as acetate and citrate, and, as such, would be considered as 'active' buffers in mineral dissolution studies.…”

Kinetics of oxidation of alcohols with tetramethylammonium fluorochromate

“…Their purity was checked by comparing their boiling points with the literature values. 16 Acetonitrile (analytical grade, Fluka) was purified and dried by distillation over P 2 O 5 . Tetramethylammonium fluoro chromate was prepared by a previously described procedure.…”
