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.

这项研究的主要目标是开发一种技术，通过在纳米材料改性的过滤载体上吸附金属来捕获金属。吸附载体将由废物制成，例如来自热电厂中煤炭燃烧的灰烬或来自纸浆和造纸工业的纤维素废物或其他废固体。基本思想是通过用纳米材料对颗粒表面进行修饰来优化吸附能力。该解决方案具有创新性，因为它将利用其他工业过程中的废物来开发一种技术，该技术将减轻采矿用水被砷和铬等金属和阴离子污染的环境影响。这一技术解决方案的受益者将是采矿公司，这将降低他们的取水成本，因为他们将在采掘过程中重复利用水。该项目的另一个有趣的方面来自于吸附剂改性载体可以重复使用，从而回收有价值的金属和阴离子。该技术的使用将有可能减少和减轻采矿业对水的环境影响，从而为其他用途提供更多优质的水。
