Magnetic filtration process, magnetic filtering material, and methods of forming magnetic filtering material
摘要：
The present invention provides magnetically responsive activated carbon, and a method of forming magnetically responsive activated carbon. The method of forming magnetically responsive activated carbon typically includes providing activated carbon in a solution containing ions of ferrite forming elements, wherein at least one of the ferrite forming elements has an oxidation state of +3 and at least a second of the ferrite forming elements has an oxidation state of +2, and increasing pH of the solution to precipitate particles of ferrite that bond to the activated carbon, wherein the activated carbon having the ferrite particles bonded thereto have a positive magnetic susceptibility. The present invention also provides a method of filtering waste water using magnetic activated carbon.
摘要（中）：

本发明提供磁响应活性炭，以及形成磁响应活性炭的方法。 形成磁响应活性炭的方法通常包括在含铁氧体形成元素的离子的溶液中提供活性炭，其中至少一种铁氧体形成元素具有+3的氧化态，并且至少一个铁素体形成元素的一部分具有 氧化态为+2，提高溶液的pH以沉淀与活性炭结合的铁氧体颗粒，其中具有与其结合的铁氧体颗粒的活性炭具有正的磁化率。 本发明还提供了使用磁性活性炭对废水进行过滤的方法。
