项目摘要
The main objective of this research is the development of a technology that would allow the capture by adsorption of metals on a filtration support modified with nanomaterials. The adsorbing support would be made of wastes such as ashes coming from the combustion of coal in thermoelectric power plants or cellulose wastes from the pulp and paper industry or other waste solids. The basic idea is to optimize the adsorbing capacity by introducing modifications to the surface of the particles with nanomaterials. The solution is innovative because it will use wastes from other industrial processes to develop a technology that will mitigate the environmental impact of water from mining that has been contaminated with metals and anions such as arsenic and chromium. Among the beneficiaries of this technological solution will be the mining companies, which will reduce their costs for getting water, because they would be reusing it in extractive processes. Another interesting aspect of the project comes from the possibility for the adsorbent modified support to be reused, allowing the recovery of valuable metals and anions. The use of this technology will make it possible to decrease and mitigate the environmental impact of the mining industry on water and thus allow a greater availability of water of adequate quality for other uses.
这项研究的主要目的是开发一种技术,该技术可以通过纳米材料修饰的过滤载体吸附金属来捕获金属。吸附载体将由诸如热电厂煤燃烧产生的灰烬或纸浆和造纸工业产生的纤维素废物或其他废物固体等废物制成。其基本思想是通过引入纳米材料修饰颗粒表面来优化吸附能力。这个解决方案是创新的,因为它将利用其他工业过程中的废物来开发一种技术,这种技术将减轻被砷和铬等金属和阴离子污染的采矿水对环境的影响。这项技术解决方案的受益者之一将是矿业公司,这将降低他们取水的成本,因为他们将在开采过程中重新使用水。该项目的另一个有趣的方面来自于吸附剂修饰载体的重复使用的可能性,允许回收有价值的金属和阴离子。这项技术的使用将有可能减少和减轻采矿工业对水的环境影响,从而使有更多的高质量的水供其他用途。
