Experimental study of nitrite accumulation in pre-denitrification biological nitrogen removal process

WU Xuelei, CHEN Lunqiang, PENG Yongzhen, WANG Pu, WANG Yayi

Frontiers of Environmental Science & Engineering 2008, Volume 2, Issue 2,   Pages 236-240 doi: 10.1007/s11783-008-0008-x

Abstract: the average nitrite accumulation rate at 91%., but nitrite accumulation rate was still as high as 90%.From the 38th day the nitrite accumulation rate decreased to 15%–30% linearly.Until the 83rd day the nitrite accumulation rate began to increase to 80%.bacteria when DO concentration was kept at 0.5 mg/L, nitrite accumulation occurred.

A simple, azulene-based colorimetric probe for the detection of nitrite in water

Lloyd C. Murfin, Carlos M. López-Alled, Adam C. Sedgwick, Jannis Wenk, Tony D. James, Simon E. Lewis

Frontiers of Chemical Science and Engineering 2020, Volume 14, Issue 1,   Pages 90-96 doi: 10.1007/s11705-019-1790-7

Abstract: We describe the synthesis and evaluation of an azulene-based chemodosimeter for nitrite.The probe was found to undergo two distinct color changes upon introduction aqueous nitrite ion.A near-instant formation of a grey color provides a qualitative indication of the presence of nitriteThe azulene probe exhibits 1:1 stoichiometry of reaction with nitrite in water, and is selective fornitrite over other anions.

Genotype variations in accumulation of cadmium and lead in celery (

Kun ZHANG, Jianbing WANG, Zhongyi YANG, Guorong XIN, Jiangang YUAN, Junliang XIN, Charlie HUANG

Frontiers of Environmental Science & Engineering 2013, Volume 7, Issue 1,   Pages 85-96 doi: 10.1007/s11783-012-0399-3

Abstract: These genotype variations in Cd accumulation are sufficiently large to help reduce Cd contamination riskCd accumulation of the Low-Cd-Accumulative genotypes is significantly positive correlated with Pb accumulationThe presence of high-Pb contamination in soil promoted Cd accumulation in shoots of celery.

Effects of nitrite on phosphate uptake in anaerobic-oxic process

LI Jie, XIONG Biyong, ZHANG Shude, YANG Hong, ZHANG Jie

Frontiers of Environmental Science & Engineering 2007, Volume 1, Issue 1,   Pages 39-42 doi: 10.1007/s11783-007-0007-3

Abstract: An anaerobic-oxic (A/O) biological phosphorus removal reactor was operated to study the effect of nitritethat in addition to oxygen and nitrate (DPB, nitrate denitrifying phosphorus removal), to some extent, nitritecould also serve as an electron acceptor to achieve nitrite denitrifying phosphorus removal (DPB).uptake of DPB, however, were evidently lower than that of DPB The experiment results revealed that nitriteThe nitrite existing in the anoxic reactor made no difference to the quantity and rate of denitrifying
