実験手順

To optionally decided weight 25% of sulfuric acid (H2SO4) was dissolved aluminum hydroxide (Al(OH)3 xH2O, molecular weight:77.99) consisting of 21.03% of aluminum oxide (Al2O3), 41.65% of Silicic acid (SiO4), 5.48% of potassium (K2), 2.70% of red iron oxide (Fe2O3), 20.85% of sulfuric acid (H2SO4), and 0.63% of water. The resulting composition was mixed with potassium sulphate (K2SO4) to produce potassium alum. The potassium alum again was mixed with aluminum silicate by a mixing ratio of 1:3 and produced 24-water salt alkali metal polysilicate-sulfate chelate. By polymerizing precipitation, colloid sol having a construction of aluminum silicate molecular sieve was yielded. To this aluminum silicate molecular sieve colloid sol, 0.3% of light magnesia (MgO), 0.15% of iron oxide (Fe2O3), 3% of calcium hydroxide (Ca(OH)2), 0.75% of sodium hydroxide (NaOH), 0.10% of potassium hydroxide (KOH), and 35% of distilled water were added in sequence stirring the mixture to produce the chelate. The chelate was put into a tank and impurities therein were removed using a cleaning filter. Then, the purified chelate was placed into a cylinder chamber of a spray dryer, and passed through a spray nozzle. The chelate, after passing through the spray nozzle, contacted with hot air through a heated air valve having a temperature range of from 302° F. to 410° F., connected to the cylinder to produce dried microsphere.
