Production of N

Youkui GONG,Yongzhen PENG,Shuying WANG,Sai WANG

Frontiers of Environmental Science & Engineering 2014, Volume 8, Issue 4,   Pages 589-597 doi: 10.1007/s11783-013-0571-7

Abstract: The N O production in two nitrogen removal processes treating domestic wastewater was investigated inResults showed that N O emission happened in the aerobic phase rather than in the anoxic phase.The dissolved N O was reduced to N in the anoxic denitrification phase.Higher nitrite accumulation resulted in higher N O emission in the short-cut nitrogen removal processPulse-wise addition of 20 mg gave rise to 3-fold of N O emission in the conventional N-removal process

Frontiers of Environmental Science & Engineering 2017, Volume 11, Issue 6, doi: 10.1007/s11783-017-0976-9

Abstract: N O is a powerful greenhouse gas and plays an important role in destructing the ozone layer.This present work investigated the effects of Pd doping on N O formation over Pt/BaO/Al O catalyst.Compared with Pt/BaO/Al O , (Pt/BaO/Al O +Pd/Al O ) produced less N O and more NH during NO storageN leading to a decrease in N O formation.Most of N O formed over (Pt-Pd/BaO/Al O +Al O ) was originated from Pd/BaO/Al O component.

Abstract:

Biopesticides are attracting interest as alternatives to conventional pesticides but without many of the non-target effects, promising a better record of safety and sustainability in pest control practices. In this article we summarize and discuss the current status and future promise of biopesticides, including how biopesticides use may increase the quality and safety of the food supply.
