    Frontiers | CO2 Removal With Enhanced Weathering and

    Humankind will need to remove hundreds of gigatons of carbon dioxide (CO2) from the atmosphere by the end of the twenty-first century to keep global warming below 2 C within the constraints of the global carbon budget. However, so far it is unclear if and how this could be achieved. A widely recognized idea is to accelerate weathering reactions of minerals that

    Mar 15, 2021 The adsorption process was a spontaneous exothermic process and could be well described by a pseudo-second-order kinetic model (Baldikova et al., 2019). For the simultaneous removal of heavy metals and BPA, a new type of biochar-supported zero-valent iron (BC-nZVI) was synthesized by a green method, and BC-nZVI and persulfate (BC-nZVI/PS

    Ferroalloy - Wikipedia

    Ferroalloy refers to various alloys of iron with a high proportion of one or more other elements such as manganese (Mn), aluminium (Al), or silicon (Si). They are used in the production of steels and alloys. The alloys impart distinctive qualities to steel and cast iron or serve important functions during production and are, therefore, closely associated with the iron and steel
