“…However, the 8 h mass change plots of every day remain stable. This probably occurs because sunlight promotes rapid solution transportation and prevents salts from building up during evaporation, which is like transpiration in plants. , For the fifth 8 h, the evaporation rate of each hour decreases, and salts can be observed in the distillation tank, as shown in Figures c and S5. Intriguingly, salt crystals can be collected by continuous evaporation of 20 wt % brine, resulting in ZLD.…”
