Please correct this page! Sulfidation of heavy metals does not 'remove' them; it merely precipitates them out of solution, reducing their biotoxicity. Depending on conditions, the metal sulfides may remain stably insoluble for quite a long time, but they are liable to be resolubilised under aerobic conditions. The correct expression would be 'remove heavy metal ions from solution'. 2A02:2121:6C0:63AA:8BD:CBB2:7F48:D3B9 (talk) 21:03, 7 December 2023 (UTC)
