Effect of iron and EGTA replacement with other divalent cations (Cu2+, Mn2+, Co2+, Cr2+) and metal chelators (EDTA, citric acid) on the light emission from Fe2+-EGTA-H2O2 system. Results obtained from four series of experiments expressed as mean and standard deviation and (median; interquartile range). (A) Fe2+-EGTA-H2O2; (B) Cu2+-EGTA-H2O2; (C) Mn2+-EGTA-H2O2; (D) Co2+-EGTA-H2O2; (E) Cr2+-EGTA-H2O2; (F) Fe2+-EDTA-H2O2; (G) Fe2+-citric acid-H2O2. * vs. value of B, C, D, E, F and G, p < 0.05.
