Abstract: The present invention is directed to a stabilized hydrogen peroxide solution containing stabilizers that maintain relatively high hydrogen peroxide stability in both concentrated form and when formulated into a cleaning solution that has a pH above 6 and contains components that normally would have a destabilizing effect on the hydrogen peroxide. The stabilizers include a first cyclic amino methane diphosphonic acid compound stabilizer in combination with a second phosphonic acid based stabilizer (different from the cyclic amino methane diphosphonic acid compound), wherein the weight ratio of the first stabilizer to the second stabilizer is at least about 2:1.

Abstract: The present invention is directed to stabilized surfactant containing solutions, stabilized or inhibited against oxidative attack, comprising an amphiphilic antioxidant component.

Abstract: Waste water effluent streams are treated with hydrogen peroxide and ultraviolet radiation. Hydroxyl ions formed by action of UV on H.sub.2 O.sub.2 reduces BOD, COD, AOX and color in effluent. In the case of pulp mill effluent, some or all of the effluent can then be recycled to the pulp mill.

Abstract: A process for a continuous production of chlorine dioxide in a cooled reaction vessel subjected to an overpressure, comprising continuous addition of an aqueous solution of an alkali metal chlorate, sulfuric acid and sulfur dioxide to the reaction vessel in proportions to generate chlorine dioxide at a temperature from about 30.degree. to about 60.degree. C. and at an acidity of about 5 to about 11 N. The reaction solution containing dissolved chlorine dioxide is continuously withdrawn. At the start up of the process the reaction vessel is filled with the water solution of alkali metal chlorate, optionally containing alkali metal chloride, and the sulphuric acid with a feed concentration of from about 20 to about 60 percent by weight whereafter the flows are adjusted to correspond to the production rate. Finally sulfuric dioxide is added so slowly that no gas phase is formed and the sulphuric acid flow is slowly increased until the suitable flow for the chosen production is reached.
