Humic acid could reduce the toxic effects of graphene oxide
WebThe demethylation of methylmercury has received substantial attention. Here, a novel chemical method for the demethylation of methylmercury is proposed. The low-toxicity graphene-fulvic acid (FA, a ubiquitous material in the environment) was synthesized without the use of a chemical reagent. The hybridized graphene-FA presented an … WebJun 11, 2024 · Pregnancy and breast-feeding: There is not enough reliable information about the safety of taking fulvic acid if you are pregnant or breast feeding.
