^a)Please note (i) the varying pH-values; (ii) that chlorite dismutases are inactivated during chlorite degradation; and (iii) the different chlorite concentration regimes used in the various laboratories. Additionally, standard reduction potentials of the Fe(III)/Fe(II) couple for some Clds have been published. NA, no activity detected.
