Ebook "Recarbonization of the biosphere: Ecosystems and the global carbon cycle" increasing amounts of carbon dioxide (CO2) are added to the atmosphere by fossil fuel combustion but the biosphere is a potential C sink. Thus, a comprehensive understanding of C cycling in the biosphere is crucial for identifying and managing biospheric C sinks. Ecosystems with large C stocks which must be protected and sustainably managed are wetlands, peatlands, tropical rainforests, tropical savannas, grasslands, degraded/desertified lands, agricultural lands, and urban lands.

In this paper, we discuss the efficiency of using a Fe2V4O13 catalyst in a heterogeneous Fenton-like process for the degradation and mineralization of Ind. We examined various factors that influence the reaction, such as the initial pH of the reaction mixture, the initial concentration of hydrogen peroxide, the amount of the Fe2V4O13 catalyst, and the reaction temperature was investigated.
