Effect of different gases on the sonochemical Cr(VI) reduction in the presence of citric acid
(Pergamon-Elsevier Science Ltd, 2020-12)
The sonochemical (850 kHz) Cr(VI) reduction (0.30 mM, pH 2) in the presence of citric acid (Cit, 2 mM) was analyzed under different working atmospheres: reactor open to air without sparging (ROAWS), and Ar, O2, air and N2 ...
Sonochemical reduction of Cr(VI) in air in the presence of organic additives: What are the involved mechanistic pathways?
(Elsevier Science, 2018-11)
The sonochemical (850 kHz) reduction of Cr(VI) (0.3 mM, pH 2, reactor open to air) was analyzed in the presence of different additives. The effects on Cr(VI) reduction efficiency of added formic acid (FA, 10 mM), citric ...
