Rare information is available on the facile preparation of biochar/sulfidated Fe composite. A facile one-step green method was established for the synthesis of magnetic seaweed (Ulva prolifera) biochar/sulfidated Fe composite (S-Fe/BC) to use excessive seaweed biomass. Removal efficiency of tetrabromobisphenol A (TBBPA) reached up to 88% in iron-sulfur treatment. Two major products were identified as bisphenol A and monobromobisphenol A, confirming the in-situ reductive debromination of TBBPA. Batch experiments showed that the removal of TBBPA was facilitated with S/Fe molar ratio of 0.2 and acidic conditions (pH = 3-7). The S-Fe/BC composite had good stability and reusability based on the cycle experiments. The removal process of TBBPA by S-Fe/BC composite might include chemical adsorption by S-Fe/BC composite, reduction debromination by S-Fe and enhanced electron transfer. The environmentally-friendly S-Fe/BC composite synthesized by one-step facile procedure showed novel potential applications in terms of pollution control of halogenated xenobiotic compounds such as TBBPA.

Plants of the division Rhodophyta, commonly known as red algae, in which the red pigment (PHYCOERYTHRIN) predominates. However, if this pigment is destroyed, the algae can appear purple, brown, green, or yellow. Two important substances found in the cell walls of red algae are AGAR and CARRAGEENAN. Some rhodophyta are notable SEAWEED (macroalgae).
Algae of the division Chlorophyta, in which the green pigment of CHLOROPHYLL is not masked by other pigments. Green algae have over 7000 species and live in a variety of primarily aquatic habitats. Only about ten percent are marine species, most live in freshwater. They are more closely related to the green vascular land PLANTS than any other group of algae.
A phylum of green plants comprising CHAROPHYCEAE (streptophyte green algae) and EMBRYOPHYTA (land plants).
A monophyletic group of green plants that includes all land plants (EMBRYOPHYTA) and all green algae (CHLOROPHYTA and STREPTOPHYTA).
Green dyes containing ammonium and aryl sulfonate moieties that facilitate the visualization of tissues, if given intravenously. They have mostly been used in the study of kidney physiology.
