在发展中国家，饮用水的砷污染是一个严重的问题，需要去除砷物种。残留砷浓度的目标值为50 ppb，处理量为500 L/天。发展中国家对净水系统的要求是当地人员的维护能力、低成本和简单的处理系统。本研究采用磁性晶种剂对胶态磁铁矿进行高梯度磁选，实现了规模化、高速化处理。
In developing countries, arsenic pollution of drinking water is a serious problem and it is required to remove the arsenic species. The targeted value of residual arsenic concentration is 50 ppb, and the processing amount is 500 L/day. The requirement for the water purification system in developing country is maintenance ability by local staff, low-cost, and simple processing system. In this study high gradient magnetic separation using magnetic seeding agent was conducted with colloidal magnetite, which realizes large-scale and high-speed processing.
