arsenate n.【化學】砷酸鹽。

arsenic

The correlations between the arsenate uptake ability of fe - oxyhydroxide - montmorillonite complexes and the duration of adsorption , initial concentration of arsenate , ion strength of the solution , acidity and temperature of environment are investigated and compared to the adsorption of arsenate on to montmorillonite and fe oxyhydroxide . results stow that fe - oxyhydroxide - montmorillonite complexes have a strong affinity for arsenate species under experimental conditions , which is supposed to influence the behavior of arsenate in soil 結果表明,蒙脫石復合體對砷酸根離子的吸附能力雖然略弱于水合氧化鐵,但卻明顯強于原鈣蒙脫石;吸附時間和砷初始濃度是影響復合體砷吸附量的主要因素;對于陳放時間不同的復合體來說,隨著復合體中鐵含量的增加,其對砷的吸附率及吸附容量均增大。

They have different properties from montmorillonite and fe oxyhydroxides such as larger specific area , different surface potential , etc . under the acidity , temperature and other conditions ( initial arsenate concentration , ion strength , duration of adsorption ) simulated to that of soil in tropical and sub - tropical area , the adsorption of arsenate on the prepared fe - oxyhydroxide - montmorillonite complexes were conducted 在參考實際土壤ph值和離子強度的條件下,分別以ph值、砷初始濃度、離子強度、吸附時間、吸附溫度為影響因素,進行了低聚合羥基鐵?蒙脫石復合體、蒙脫石原樣及水合氧化鐵吸附砷酸根離子的對比實驗;并用正交實驗方法,進一步研究了上述因素對復合體砷吸附能力的相對影響程度。

On the basis of the analysis , the possible mechanism of arsenate adsorption is also discussed 根據上述實驗結果,對吸附機理進行了探討。

The arsenate is usually formed in oxidation zones in contact with the atmosphere and free oxygen, and arsenic will precipitate with ferric hydroxide . 在與大氣和游離氧接觸的氧化帶中,常形成砷酸鹽,而且砷與氫氧化鐵一起沉淀。
