The present disclosure relates to methods of synthesizing slurries comprising ferrihydrite nanoparticles, and systems and methods employing the same. The method may include the steps of preparing an aqueous solution having ferric iron cations, halide anions, and a two-line iron promoter, and precipitating the ferrihydrite nanoparticles in the aqueous solution, thereby producing a ferrihydrite slurry. The ferrihydrite slurries may be useful in treating a polluted fluid having sulfur contaminants therein.

Hydrogen sulfide is scrubbed from a gas stream to prepare dissolved alkali metal sulfide or hydrosulfide, which is used to prepare feed electrolyte solution for electrochemical processing to generate alkali metal hydroxide in catholyte and polysulfide in anolyte, which may be recovered from an electrochemical reactor and which may be subjected to further processing to precipitate elemental sulfur. Aqueous scrubbing solution may include alkali metal carbonate capture agent to capture hydrogen sulfide in alkali metal bicarbonate The gas stream may include carbon dioxide in addition to hydrogen sulfide, and a ratio of dissolved alkali metal carbonate to bicarbonate may be increased prior to electrochemical processing.
