Redox potentials of various bleaching agents and the fiber model substances were measured in order to estimate the oxidizing power of them.Bleaching agents used were sodium hypochlorite, hydrogen peroxide, sodium percarbonate, sodium perborate and sodium hydrosulfite. On the other hand, glucose and glutathion were adopted as the model substance of cellulose and wool fibers respectively.Results obtained were as follows.1) The redox potential of sodium hypochlorite was higher in plus value than that of hydrogen peroxide. That is to say, the bleaching agents of perchlorite series had more intensive oxidation power than that of peroxide series.2) Every redox potentials of peroxide bleaching agents used in these experiments were nearly equal. Sodium hydrosulfite exhibited minus potential.3) The potential of these bleaching agents lowered with the increase of pH, with point of infection appearing in diagram.4) The potential of glucose and glutathion were lower than that of peroxide series, and with the increas of temperature the potential of that became lower.

@yamazaksv2 @akiaknp 興味深い話ですね。塩素を水に溶かした時の平衡 Cl2 + H2O ←→ H+ + Cl- + HClO HClO ←→ H + ClO- (この平衡は中酸性側ではほとんど左のまま) に酸を加えると左にシフトして実効塩素濃度が高まるのと同等のグラフと思います。 もとの論文はこちらですね。 https://t.co/W20qmAoUWN
