Over use of N fertilizers, most commonly as urea, had been seriously concerned a major source radiative (Nr) for severe environment impacts through leaching, volatilization, and N2O emission from fertilized croplands. It well known that biochar could enhance retention efficiency by crops in amended In this study, granular biochar-mineral urea composite (Bio-MUC) was obtained blending with green waste supplemented clay minerals bentonite sepiolite. This Bio-MUC material firstly characterized microscopic analyses FTIR, SEM-EDS STEM, subsequently tested leaching water column experiment supply maize pot culture, compared to conventional fertilizer (UF). Microscopic indicated binding particle surfaces the composite. over 30 days, cumulative release NH4+-N dissolved organic carbon (DOC) significantly smaller >70% 8% than UF. culture growing 50 total fresh shoot enhanced 14% but root 25% under study suggested shown slow releasing growth promoting soil, relative urea. Such effect be related mainly biochar/mineral partly bonds Bio-MUC. Therefore, agro-wastes used combined organo/mineral replace mineral so reduce on global Nr. Of course, how such would impact process soil-plant systems deserve further field studies.

Magnetic Nanoscale Zerovalent Iron Assisted Biochar: Interfacial Chemical Behaviors and Heavy Metals Remediation Performance

ACS Sustainable Chemistry & Engineering, Год журнала: 2017, Номер 5(11), С. 9673 - 9682

It has been reported that zerovalent iron can help biochar improve efficiency in heavy metal (HM) absorption, but the surface chemical behaviors and HM removal mechanisms remain unclear. We successfully synthesized magnetic nanoscale assisted (nZVI-BC). The porosity, crystal structure, carbon/iron atom state, element distribution were comprehensively investigated to understand nZVI-BC's interfacial mechanisms. clearly revealed formation of a Fe0 core–Fe3O4 shell on surface/pores/channels biochar. With combination nanoparticles biochar, C–O/COOH groups cracked with C═O/C═C, indicating C–O–Fe acted as an electron acceptor during reduction reaction. also demonstrated stabilization was dramatically improved nZVI-BC, while more reduced better homogeneity observed. These results, showing would increase our understanding Moreover, demonstration superior ability multiple (Pb2+, Cd2+, Cr6+, Cu2+, Ni2+, Zn2+) from solution provide breakthrough making feasible material for removing polluted water resources.
