Nanosilica A-300 and A-50 S =232 or 297 and 52 mVg, respectively) was heated at 673 K for several hours to remove residual HCl and other adsorbed compounds (Gun ko et al. 2006i). Proteins such as BSA ( Allergen, Stavropol, Russia, molecular weight Wm 67 kDa), gelatin (Merck, powder food grade), ovalbumin (Wm 44 kDa), and ossein ( Indar, Kiev, Ukraine, 24.5 4.5 kDa) polymers such as PVP ( Biopharma, Kiev, 12.6 2.7 kDa), PVA ( Stirol, Severodonetsk, Ukraine 43 7 kDa), and PEG (Flnka, BV 2, 20 and 35 kDa) were used in QELS experiments to analyze the kinetic interactions of co-adsorbates (Gun ko et al. 2006i). 

To fabricate the composites, 1, 4, 7 and 10 vol % food grade bovine gelatin P-11 solutions in distilled water were used. The samples of porous HA ceramics were immersed in the polymer solution under a vacuum of 1.33 Pa for 10 or 30 min, and without vacuum for 30 min. The temperature of the solution was 40°C. After vacuuming at this temperature, the samples were dried for 24 h in an air furnace [20]. 

With the system that employed these raw materials, numerous advantages of fluid mixtures were established, but a need to improve the economics of the procedure was obvious. Pure electric-furnace acid is much more expensive than wet-process acid, so ways were sought to use the cheaper but impure wet-process acids. Direct ammoniation of wet-process acid causes precipitation of numerous impurities as an intolerable, gelatinous sludge. Also, plant-food solubilities are undesirably limited in the orthophosphate system, so the concentration (grade) of the product made with electric-furnace orthophosphoric acid was limited to 8-24-0. A series of developments by TVA led the way to solving both of these problems.
