 Water scarcity is a global issue that affects millions of people, causing severe economic, social and environmental consequences. It can also have detrimental effects on agriculture, industry and households resulting in decreased quality of life. Governments, communities and individuals must work together to conserve water resources and implement sustainable water management practices. Additionally, the improvement of existing water treatment methods and the development of new ones is necessary. We have investigated the potential of green aerogels in removing ions from water. Using principal component analysis, PCA, we found that the three types of aerogels, nanosellulose-, chitosan- and graphene-based, had similar efficiencies in ion removal. Furthermore, PCA allowed us to visually compare the various properties of the aerogels, such as their physical-slash-chemical characteristics and adsorption features.
