The pollutant was dry crystal copper sulfate pentahydrate CuSO4•5H2O (Sigma Aldrich©, UK). Imitating circumstances of potential leakage or spillage associable with anthropogenic activities, 0.7 g/L of the pollutant was applied. Copper extraction was conducted using a complex treatment: 1) zinc-reinforcement of zeolite: The zeolite of choice (ZSM-5) was applied in its raw (zinc-free form) as the baseline, or zinc-reinforced forms (via partial zinc gel coating or zinc plasma sputtering), -/+ rare-earth magnet, in the absence of aquacultured faba bean plant V. faba. 2) Vicia faba as the model bio-trap of Cu 2+ was applied alone.
