Summary: Organic acid digesters are gaining popularity in municipal nutrient recovery technologies, but the current industry standard BioWin modeling software fails to accurately predict their performance. By adjusting parameters such as pH inhibition thresholds, growth and decay kinetics, and hydraulic residence times, we have improved the modeling accuracy of acid phase digestion reactors in BioWin. These refinements allow for easy modeling of acid digesters and prediction of changes in wastewater treatment technologies.

Summary: In this work, a portable analytical system based on point discharge chemical vapor generation atomic emission spectrometry (PD-CVG-AES) coupling with gold filament enrichment was designed. The highly sensitive analysis of Hg2+ indirectly realized the detection of ascorbic acid (AA). The measurement is based on the fact that Ag+ can decrease the concentration of Hg2+ by forming Ag-Hg amalgam in the presence of the reductant SnCl2, while AA can pre-reduce Ag+ to Ag0, leading to the generation of silver nanoparticles (Ag NPs). The developed novel analytical strategy broadens the application of microplasma-based AES and offers a higher level of sensitivity compared to current AA detection techniques.
