1.建立了一种在不被二氧化硅污染的情况下测定含二氧化碳碱性溶液的pH的方法。2.方程式2A102~+2H30+>；A1203·3H20代表了二氧化碳在60℃时从铝酸钠溶液中沉淀氧化铝的机理。3.三水铝石在离子强度为0.6~0.7、pH为11.20~11.45的铝酸钠溶液中的溶解度约为5×10~(-3)摩尔/升。
1. A method was developed for measurement of the pH of alkaline solutions containing carbon dioxide without their contamination by silica. 2. The equation 2A102~+ 2H30+—> A1203· 3H20 was found to represent the mechanism of the precipitation of alumina from sodium alumínate solutions by carbon dioxide at 60. 3. The solubility of gibbsite in sodium alumí-nate solutions of ionic strength 0.6 to 0.7 and pH 11.20 to 11.45 was estimated to be about 5 X 10” 3 mole per liter.
