砷酸根离子 meaning in English
arsenate ion
Examples
- 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
在参考实际土壤ph值和离子强度的条件下，分别以ph值、砷初始浓度、离子强度、吸附时间、吸附温度为影响因素，进行了低聚合羟基铁?蒙脱石复合体、蒙脱石原样及水合氧化铁吸附砷酸根离子的对比实验；并用正交实验方法，进一步研究了上述因素对复合体砷吸附能力的相对影响程度。 - 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
结果表明，蒙脱石复合体对砷酸根离子的吸附能力虽然略弱于水合氧化铁，但却明显强于原钙蒙脱石；吸附时间和砷初始浓度是影响复合体砷吸附量的主要因素；对于陈放时间不同的复合体来说，随着复合体中铁含量的增加，其对砷的吸附率及吸附容量均增大。
