Effects of Several Manufacturing Conditions on Acid Consuming and Adsorbing Capacities of Aluminum Silicate

합성규산(合成珪酸)알루미늄의 제산능(制散能) 및 흡착능(吸着能)에 미치는 제조조건(製造條件)의 영향(影響)

The effects and the optimum manufacturing conditions for the preparation of synthetic aluminum silicate which has acid-consuming power and adsorbing capacity were investigated. The results are as follows: 1. The adsorbing capacity was affected by the mixing order of the reactants, that is, the excellent ones were obtained by the method which add the sodium silicate solution to the potassium alum solution. 2. Even though preparing by the bane manufacturing condition, the acid-consuming power is superior to the adsorbing capacity. 3. According to the Box-Wilson Plan, the optimum reaction conditions are concentration of sodium silicate solution; 38% w/w, settling time; 43 hours at room temperature, drying time; 13 hours at $110^{\circ}C$.
