Abstract:In this study, variations of hydrogen production were investigated with food waste fermentation in the presence of heavy metals. Hydrogen production was 79.48 mL/g COD with fermentation of food waste. In the presence of 1 mg/L of zinc, the hydrogen production was decreased about 60%. When the copper is present, the production of hydrogen is severely inhibited, while the coexistence of copper with zinc relaxes the inhibition of copper and restores hydrogen production. Butyric acid or acetic acid was observed as… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
