Abstract:
1. A system for preparing a mixed composition for treatment of a surface, the mixed composition being formed from two initially separate composition parts, the system comprising: a first chamber containing an oxidant first part comprising hypohalous acid or a hypohalite; and a second chamber containing a reductant second part comprising a nitrite, wherein the first and second chambers are initially separated from one another to prevent premature mixing of the first and second parts; wherein a molar ratio of the reductant to the oxidant is from 4:1 to 1.1:1; mixing the oxidant first part with the reductant second part to form a mixed composition, wherein the mixed composition has a pH from 7 to 11; wherein the mixed composition provides oxidizing benefits for a limited duration, the oxidant reacting with the reductant to reduce the oxidant concentration so as to prevent or minimize negative side effects associated with prolonged oxidant exposure longer than the limited duration.
