Fig. 4: Performance of GAH in clean water selective harvesting.
From: Multifunctional solar water harvester with high transport selectivity and fouling rejection capacity
a, Vapour generation rate plots of GAH and bare water under one standard sunlight. b, Concentrations of toluene, dichloroethane (EDC), dioxane and phenol in raw sewage (yellow column) and GAH extracted water (red column). Grey column indicates drinking water standard adopted from World Health Organization or Environmental Protection Agency. c, K+, Ca2+, Na+ and Mg2+ concentration in raw sewage (yellow column) and water extracted by GAH (red column). d, Images of culture dish growth with raw lake water (right) and GAH extracted water (left). e, UV–Vis absorption spectra of methyl red, methylene blue solution and GAH extracted water. Images at the right side show the colour of solution of red (methyl red, MR) and blue (methylene blue, MB) to colourless and transparent (GAH extracted water).
