Abstract: Peroxycarboxylic acid compositions comprising compatible ionic compounds to deliver conductivity signals to enable monitoring of the peroxycarboxylic acid concentration by conductivity when diluted for use are disclosed. Methods of measuring peroxycarboxylic acid concentration by conductivity are also disclosed. Beneficially, conductivity measurement allows a user to determine concentration of the peroxycarboxylic acid at a point of use without cumbersome titration steps to determine the concentration providing various benefits at an application of use.

Abstract: Disclosed are nitrogen-containing heterocyclic compounds of relatively low aquatic toxicity and methods of using the heterocyclic compounds as corrosion inhibitors. The present method is used to inhibit corrosion of a metal surface in contact with an aqueous system using pyrazole derivatives, and provides enhanced protection against corrosion of metals in aqueous systems. The method comprises the use of corrosion inhibitors that are generally resistant to halogen attack and provide good corrosion resistance in the presence of oxidizing halogen-based biocides. Formulations comprising pyrazole derivatives are also disclosed.
