摘要
氧化铁涂层砂和未涂层石英砂除砷过滤实验比较表明,氧化铁涂层砂除砷效果显著,去除率达95％以上,基本遵循低pH,高去除率的规律;除砷吸附等温线属于Langmuir型,单层吸附。
The performance of iron-oxide-coated sand(IOCS) and uncoated quartz sand in filtration for arsenic removal has been studied. IOCS removed arsenic from water reached the level of >95%, and the removal efficiency increased with decrease of pH value. The adsorption isotherm of arsenic removal belongs to Langmuir adsorption model and was valid for single-layer adsorption.
