脫砷 的英文怎麼說
中文拼音 [tuōshēn]
脫砷
英文
dearsenication-
Such complexes might have affinity for detrimental inorganic oxyanions such as arsenate, a common toxic contaminant in soils. the purpose of this study is to investigate the influence of environmental conditions on the adsorption of arsenate on fe - oxyhydroxide - monlmorillonte complexes, which is significant to agrology, geochemistry and environmental science
本研究即以南方的土壤環境條件為參考，模擬在ph = 5時的酸性氧化條件下，土壤中低聚合羥基鐵?蒙脫石復合體的形成、物化性特徵及其吸附砷酸根陰離子的行為。Taking the example of china tin gruop co., ltd hechi metallurgy and chemical industry, the article details the production processes, technology conditions and production practice of removing arsenic from the second caustic sludge and lead from the second lead sludge
摘要文章以華錫集團河池冶金化工廠精煉生產工藝為例，詳細介紹了採用二次堿渣進行脫砷，二次鉛渣進行脫鉛的生產流程、工藝技術條件及生產實踐。The costs of production have been reduced by 10 percent since the method was adopted, and benefits have aslo achieved above one million rmb every year
該廠自從採用二段脫砷二段脫鉛方法，降低生產成本達10 %以上，年創效益達100萬元以上。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；並用正交實驗方法，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。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於水合氧化鐵，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。分享友人
