地下水是最重要的饮用水来源之一。地下水砷（As）污染是世界范围内的一个严重问题，特别是在孟加拉国、印度和东南亚。使用适当且易于获得的吸附剂进行吸附是一种有前途的除砷方法，适用于农村地区。本工作旨在研究使用红土（LA）和铁改性活性炭（AC-Fe）连续组合作为吸附剂的吸附柱从合成地下水中去除砷。 The effect of ratio LA/AC-Fe, flow rate, initial arsenic concentration and pH to the breakthrough time were investigated.通过间歇实验研究了吸附平衡和吸附动力学。结果发现，这是一种有效且可行的地下水砷处理方法，可立即应用于农村地区。
Groundwater is one of the most important sources for drinking water. Arsenic (As) contamination of groundwater is a serious problem worldwide, especially in Bangladesh, India and South East Asia. Adsorption using appropriate and readily available adsorbents is a promising method for the removal of arsenic with applicability in rural areas. This work aims to study the removal of arsenic from synthetic groundwater using an adsorption column by sequential combination of laterite (LA) and iron-modified activated carbon (AC-Fe) as adsorbents. The effect of ratio LA/AC-Fe, flow rate, initial arsenic concentration and pH to the breakthrough time were investigated. Adsorption equilibrium and adsorption kinetics were also studied through batch experiment. The result was found to be an efficient and feasible approach for arsenic treatment from groundwater for ready applicability in rural areas.
