Lead and arsenic are two of the most toxic common water contaminants. We report on a new type of portable and sustainable device designed for arsenic and lead removal from highly contaminated water sources. The device utilizes a combination of granular activated carbon (GAC) and an electrochemical deposition technique that increases the device's decontamination performance. This is the first low cost portable device that is designed to sustainably clean highly contaminated drinking water. The device removes 1 ppm of arsenic and lead simultaneously to reach a drinkable level using a 1.5 V AA battery as the power source. Using the device we were able to clean 1 L of highly contaminated water, 1 ppm of both metals, in 20 min before a regeneration process was required. We also report on strategies for the sustainable regeneration of the device and investigated the mechanism behind the removal and regeneration process. Finally, we discuss the use and scale up possibility of this approach as a temporary solution for water purification in low income populated areas.

便携式且可持续的活性炭基设备，用于电辅助水净化

铅和砷是两种毒性最高的常见水污染物。我们报告了一种新型的便携式可持续设备，旨在从高度污染的水源中去除砷和铅。该设备结合了颗粒状活性炭（GAC）和电化学沉积技术，可提高设备的去污性能。这是设计用于可持续清洁高度污染的饮用水的第一款低成本便携式设备。使用1.5 V AA电池作为电源，该设备可同时去除1 ppm的砷和铅，达到可饮用的水平。使用该设备，我们能够在需要再生过程之前的20分钟内清洗出1 L的高污染水（两种金属均为1 ppm）。我们还报告了设备可持续再生的策略，并研究了去除和再生过程背后的机制。最后，我们讨论了这种方法在低收入人群地区作为水净化的临时解决方案的使用和扩大的可能性。
