GRAFREN Heavy Metals Removal (HMR) - Graphene Oxide Water Purifying Membranes

Contribution of diverse industries to the heavy metals pollution of the environment

Problem Adressed

 “Clean, accessible water for all is an essential part of the world we want to live in and there is sufficient fresh water on the planet to achieve this. However, due to bad economics or poor infrastructure, millions of people including children die every year from diseases associated with inadequate water supply, sanitation and hygiene” (Sustainable Development Goals, declated by United Nations, Goal 6: Ensure access to water and sanitation for all 1).

Modern technical progress and industrial manufacture growth affects detrimentally the environment (Fig. 1). At present more than 80 percent of wastewater resulting from human activities is discharged into rivers or sea without any pollution removal. As a result, at least 1.8 billion people globally use a source of drinking water that is contaminated [1]. Certain areas, especially in the industrially developing countries have totally poisoned water, forbidden for drinking and bathing. 





This project will clarify the technical and juridical feasibility of graphene oxide (GO) coatings for water purifying. The idea is based on the research results, generated at Linköping University: earlier it was shown, that GO can adsorb heavy metals (Hg, Pb, Cr, Cd, Co etc) from aqueous solution. Due to this property in conjunction with unique thickness of graphene the innovative product can be designed – water filtering membranes. Thus, the project will address the technical feasibility of coating GO onto porous fibre based membrane, studying the approaches by literature review and then fabricating the samples by most appropriative method. Prior to that, the method and approaches will be analysed in terms of Freedom of Operation analysis, in order to clarify the IP landscape of the idea and defining its juridical feasibility.
