11288870-6	2001	The recombination of CO2*- to give oxalate directly is estimated to have a contribution of <25%.	Oxalates	35-42	complement C2	Homo sapiens	21-24	
35483260-6	2022	Electron paramagnetic resonance (EPR) and quenching experiments demonstrated that oxalate was activated by holes under light to produce  CO2- and enhanced the generation of additional  OH and  O2-, further contributing to the oxidation of As(III) and reduction of Cr(VI).	Oxalates	82-89	complement C2	Homo sapiens	137-140	
2164694-4	1990	We ascribe this spectrum to the CO2- radical formed from the oxalate ion.	Oxalates	61-68	complement C2	Homo sapiens	32-35	
33241685-5	2020	In the continuous phase, the oxidation of oxalate (C2O42-) produces a strong reducing agent, CO2 -.	Oxalates	42-49	complement C2	Homo sapiens	93-96
