近期, 自伦敦帝国理工学院 and more more large 学 科研人员 combined as, development 出 一 types tool 经济效益 sponge tool, use for waste water in 原油进行吸附, about/regarding research 文章发 table/sheet in 《自然—— sustainable property 》(Nature Sustainability)杂志 upper.

in production process in, by 原油污染 石油 waste water amount tool has separation can 观 数字, this 也直接反映出石油 浪费以 and for water and and other ring 境 污染. in cost and ring pressure lower, decrease/reduce waste water demand more promote related technology generate. upper 科学家早 front already through utilizing ultra- wet lubricating sponge 进行油 water mixed combined material separation 离, is will this type of formed used for waste water upper 却并不久.

据科研人员 introduction, this is types innovation surface engineering sponge (SEnS), using/adopting polyurethane ester foam as is made as material, will surface chemical, electrical 荷, coarse degree has machine combined, can achieve for micro 滴 吸附. 帝国理工学院 chemical engineering 系博士Pavani Cherukupally此 front development types 海棉 早期版本, although in this in sponge rate can to 95%, is consumption has 3 small 时, this ratio industrial 处理程序 use time also need 久, in 当时并未 can to application.

but also 我们知道, although polyurethane ester foam tool has good property can, is usually this type of material can in acid property conditions lower performance relatively good as 效果. is improvement this technology difficult research in research process in add 入 一 types nano silicon pellets can polyurethane ester foam material 质, chemical property and electrical coating, make sponge suitable ring acid alkali degree conditions 进一步拓 wide.

research 结果显示, in can as acid alkali degree conditions lower, 该吸油 sponge in 理夫绪兹-凡德瓦尔 force (Lifshitz-van der waals) and electrical force function lower can achieve fast speed 吸附原油 micro 滴, micro in acid property, in property and alkali property conditions lower remove efficiency 达95~99%. in pH value lower, 10 separation inner, types sponge can currently use amount waste water in 92% 原油 micro 滴, although rate 略逊于早期版本, efficiency to non large improves.

value attention/notes is, SEnS sponge also tool has relatively good can heavy utilizing property. sponge solvent agent rear can will 油萃取而出, rear sponge can again used for 原油吸附. and sponge upper belt/tape has nano silicon pellets coating can in will micro 滴紧紧“抓住”, in sponge surface formed surface coating, water can from sponge in 滤并流出, ensure 滤 效果.

in addition, 基于该 types sponge property can belt/tape 灵感, 科研人员 positive in combined as research from salt water in remove fine 菌, table/sheet 示: “尽 tube/pipe sponge is industrial waste water design, is in water or conditions in use can use improvement future 因污染泄漏而 belt/tape ring issues ”. but also 科研人员 also to, 他们希望 in gas, textile 业, 采矿业 and other industry production in can use this type of sponge, for in heavy metal, 病原体 and other material 质 清 remove, 并希望该 technology future can development China can negative 担 起.

currently research already in for this type of sponge modified 并尝试 industrial application, 也许不久 will will has machine in industrial production in use this type of technology.
