Matrix Effect Assessment of an Ion Chromatographic Method to Determine Inorganic Anions in Wastewater
(2018-07-01)
Inorganic anion monitoring is essential for bioreactor operation and is related for pollution control or energy and products recovery. However, there is a lack of studies validating methods for inorganic anions analyses ...
Photo-Fenton degradation of a herbicide (2,4-D) in groundwater for conditions of natural pH and presence of inorganic anions
(Elsevier Science, 2019-06)
The effects of four inorganic anions (Cl-, SO42-, HCO3-, NO3−) usually present in groundwater were investigated on the photo-Fenton degradation of 2,4-dichlorophenoxyacetic acid (2,4-D). A kinetic model derived from a ...
An Electron Spin Resonance (ESR) investigation of potential ligands of inorganic interest with nitro substituents
(MARCEL DEKKER INC, 2002)
Electron Spin Resonance spectra were obtained of the salicyliden-2-imino-5-nitropyrimidine (1(.-)), N,N-bis(5-nitro-salicyliden). ethylendiamine (2(.-)), 2-hydroxy-5-nitro-benziliden-5-iminoquinoline (3(.-)) anion I radicals ...
On line pre-concentration for simultaneous determination of low molecular weight organic acids and inorganic anions in Amazonian river water samples employing ion chromatography with conductivity detection
(Instituto Nacional de Pesquisas da Amazônia, 2009)
An ion chromatography procedure, employing an IonPac AC15 concentrator column was used to investigate on line preconcentration for the simultaneous determination of inorganic anions and organic acids in river water. Twelve ...
Study on the formation of mesoporous molecular sieves in the presence of various anions
(Elsevier Science BvAmsterdamHolanda, 1999)
Indirect determination of chloride and sulfate ions in alcohol fuel by capillary electrophoresis
(Springer, 2004-09-01)
A capillary zone electrophoresis method using indirect UV detection for the analysis of chloride and sulfate in alcohol fuel samples was developed. The anions were analyzed in less than 3 min using an electrolyte containing ...
