中文摘要 | 在模擬酸雨管柱淋溶試驗中,發現土壤對硫酸根之吸附行為可以分成三類。第一 類土壤如, 阿里山( Bt )、塔塔加( Bw1 )、小雪山( B )、東寶津寒山( Bt1 )、 祝山( Bt2 )、太平山( Bhs )、思源啞口( Bs )、石棹( Bw )之硫酸根吸附尚未達 到平衡,而以去離子水淋洗而脫附出來的硫酸根較多; 第二類土壤如蓮華池( B )、太平 山( Bw1 )、太平山( Bw2 )、石棹( A )、風口( Bw )、塔塔加( A )、思源啞口 ( A )之硫酸根吸附行為,主要集中在初期十幾個孔隙體積的淋溶階段, 且其硫酸根脫附 反應平衡時間較第一類供試土壤短;第三類土壤如阿里山( A )、蓮華池( A )、太平山 ( Ao )、太平山( E )、 東寶津寒山( A )、 太平山( A )、祝山( A )、風口 ( A )之硫酸根吸附能力相當低,在初期幾個孔隙體積即已快速達到平衡,其中有些土壤 甚至有脫附的現象,而其以去離子水抽取的硫酸根脫附行為,亦在短時間內即已達到平衡。 A 層土壤的硫酸根總吸附量較 B 層土壤少,供試土壤吸附的硫酸根, 大部份皆可被去離子 水淋溶而脫附出來。 |
英文摘要 | In soil column leaching tests, soils could be classified into three groups. The first group of soils, i.e., A-Lie-Shan (Bt), Ta-Ta-Chia (Bw1), Shaw-Sueh-Shan (B), Tong-Pau-Chin-Han Shan (Bt1), Chu-Shan (Bt2), Ta-Ping Shan (Bhs), Shih-Yan-Ya-Kao (Bs), and Shi-Chou (Bw) did not equilibrate with sulfate solutions. These soils could easily desorb native soil sulfate by water extraction. In the second group of soils, i.e., Lieh-Hua Chi (B), Tai-Ping Shan (Bw1、 Bw2), Shi-Chou (A), Fong-Kou (Bw), Ta-Ta-Cha (A) and Shih-Yan-Ya-Kao (A), the behavoir of the sulfate adsorption was concentrated in the range of 1-20 pore volumes of leaching study. It is shown that the equilibrate time with sulfate adsorption versus solutions was faste than the first group of soils. The third group of soils, i.e., A-Lie, Shan (A), Lien-Hua-Chi (A), Tai-Ping Shan (Ao, A, E), Tong-Pau-Chi-Han Shan(A), Chu Shan (A), and Fong-Kou (A), possessed low ability of sulfate adsorption. It is shown that a rapid equilibrium with in several pore volumes in leaching experiments. These soils also showed sulfate desorption with water extraction. The total sulfate adsorption by B horizons was greater than that of A horizons. Sulfate adsorption by most soils can be leached out by water extraction. |
