Using acetic, sulfuric, hydrochloric, phosphoric and perchloric acid as acidifying agent, gelation time of monostlicic acid of different concentration at various pH was determined. All the log t--pH curves were of N-Shape. The pH value at the minimum point of each curve shifted upward and to- ward the left as concentration of silicic acid decreased. With acetic acid as acidifying agent, the gelation curve had the same tendency when concentra- tion of silicic acid changed, but with a strong acid, as hydrochloric or sulfuric, no such shift was observed at the maximum point. When log t of the minimum points of each set of gelation time curves were plotted against the corresponding log T_(?), straight lines were always obtained. However, the slope of the lines was about -3 instead of -2 as required by the theoretical equation. This is found to be due to the effect of the salt formed in the process of acidification of sodium monosilicate. When the concentration of sodium monosilicate used was kept constant and different amounts of a salt corresponding to the acid used as acidifying agent were added, the gelation curves obtained indicated that, in case when either hydrochloric acid or sulfuric acid was used as acidifying agent, the added salt had a little pro- motion effect at the maximum point but did not change the pH value. However, with the minimum points of all the curves and the maximum of that of acetic acid as acidifying agent, they all shifted downward and rightward. When log t was plotted against log T_s, straight line was also obtained, with a slope of about -1, indicating that getlation time of monosi- licic acid is inversely proportional to the first power of the concentration of salt. When the concentration of salt was kept constant and that of silicic acid varied, pH of the maximum points of all gelation curves no matter which acid was used as acidifying agent remained constant, while that of the minimum points changed but a little. And in all cases, when log t was plotted against log T_(?), a straight line was always obtained, the slope of which was -2, indicating experimental results were in complete accord with our theoretical expression. When the effect of added salt is included, the expression should be modified slightly and takes the following form: log t=log C'--(2+n')log T_A--log (1+β_1[H~+]+β_2[H~+]~2+β_3[H~+]~3)~2/β_2β_3 [H~+]~3 --log(β_1/β_2+[H~+]~2).

以乙酸、硫酸、盐酸、磷酸及高氯酸为胶凝剂,测定了不同浓度单硅酸在不同pH的胶凝时间,得到了一系列硅酸浓度与胶凝时间的曲线。曲线皆为N形。所有曲线的最低点和乙酸曲线的最高点的pH值,皆随硅酸浓度的减少而向左上方移动,但盐酸和硫酸曲线最高点pH值无明显变化。各组曲线最低点的log t和相应的log T_A昔为直綫关系,但直线斜率昔等于-3,而不是表达式中的-2。这是由於酸化过程所产生的盐的效应。在单硅酸浓度恒定时,加入不同量与所用胶凝剂相当的盐,从所得的胶凝曲綫表明,盐对发盐酸及硫酸为胶凝剂的曲线最高点略有促进作用,而不改变pH值。但所有曲线最低点及乙酸曲线最高点,昔随各种盐浓度的增加而向右下方移动。每组曲线最低点的log t和log T_s皆为直线关系,直线斜率在-1左右,表示盐浓度与胶凝时间的一次方成反此。在固定盐浓度,改变单硅酸浓度的实验中,所有盐酸、硫酸、硝酸、乙酸及磷酸的各套胶凝曲线的最高点pH值皆不改变,而最低点的pH值只微有不同,每组曲线的不论最低点或最高点,它们的log t和log T_A皆有直线关系,其直綫的斜率都在-2左右,和表达式的要求完全符合。故包括盐效应的硅酸聚合而成凝胶的表达式改进为:

酸雨由于其全球性而被看作为首要的环境问题之一。它对生态系统的综合效应还不十分清楚,但已知它们有潜在的严重危害。酸雨可能改变营养物从土和叶的淋溶率;酸化河湖而减少或灭绝鱼类种群;此外还影响土壤微生物,特别是固氮微生物;影响致病细菌和真菌的行为;增加从土壤摄入有毒金属;可能与除草剂及其他合成化合物产生协同作用。防治酸雨的根本途径之一是煤资源的综合利用。
