“…The research work of Bagla et al, has examined and justified an innovative and concrete role of DCP in the bioremediation of toxic metal pollutants and hazardous radionuclides from the pool of various effluents using Radiotracer technique. Notable heavy metal pollutants like trivalent and hexavalent chromium, cadmium [39], mercury [40], silver [41], zinc [42] have been eliminated from aqueous systems using DCP as a biosorbent. Similarly, radionuclides commonly found in radioactive waste - 60 Co, 90 Sr and 137 Cs [43,44], have been removed from simulated systems of reactor and reprocessing waste.…”

Water-Food-Energy (WFE) Nexus regulates biosphere and irrespective of alphabetical or chronological order, it must have synergy for the sustainability of life. Population, Pollution and current Pandemic- COVID has made it vivid to entire scientific community that unless we strengthen this trio, our progressive humanity is sure to collapse. Humic Substances (HS), the originator of the life has promising utilization in almost every sectors of life, reinforcing WFE Nexus. This chapter dedicates to novel unearthed HS, Dry Cowdung Powder (DCP) and its unique contribution in sustaining the triangle of life, WFE. DCP has been employed as humiresin for bioremediation of wastewater containing heavy metals and radionuclides. The known candidate for Biorhexistasy, DCP increases soil fertility, minimizes erosion and acidification. It is also extensively explored as biofuel, green and clean source of energy. ‘Nothing of Nature is a Waste’ and ‘Waste is a Commodity’ aptly describes DCP, the sustainer of WFE Nexus.

110 m Ag, comes from pressurized water reactor units, has become one of the major radionuclides affecting the surrounding environment. The chemical species of 110 m Ag are controlled by additives or impurities during operation process of nuclear power plant. Colloidal state (named Ag 0 ) and ionic state are main chemical forms. It is difficult to remove Ag 0 by commercial ion exchange resin because the colloidal particles have different sizes and low charge. The oxidative resin loaded with Fe 3+ were prepared and used for removal of colloidal Ag from aqueous solution. The influence factors such as resin dosage, adsorption time and initial concentration of Ag 0 were investigated through batch experiments. The adsorption efficiency of the oxidative resin towards Ag 0 in aqueous solution could reach 92.5% under pH 7. The adsorption process corresponds to the Langmuir adsorption model and pseudo-second-order kinetic equation. XPS analysis clearly shows the presence of binding energy peaks of Fe 2+ and Ag + , which indicates the adsorption mechanism towards Ag 0 is based on the combined actions of redox and ion exchange.
