Stable, aqueous solutions of chlorine dioxide and methods for producing stable, aqueous solutions of chlorine dioxide are disclosed. Generally, the chlorine dioxide solutions of the invention are aqueous solutions containing about 1000 ppm by weight or less of total impurities and/or 10 ppm or less of manganese and iron combined. The aqueous chlorine dioxide solutions are storage stable for at least 90 days at 25&#xb0; C. and maintain at least 75% of the initial chlorine dioxide concentration. Methods of preparing, using and transporting the chlorine dioxide solutions are also disclosed.

Storage-stable aqueous solutions of chlorine dioxide and methods for preparing and using them

The present invention is for extremely pure solutions of chlorine dioxide, methods for making such solutions and to compositions and methods for storing, shipping and using such solutions. Generally, the chlorine dioxide solutions of the invention are aqueous solutions containing about 2500 ppm or less of total impurities. The chlorine dioxide solution can be prepared by passing dilute highly pure chlorine gas through a bed of substantially solid sodium chloride and contacting the resulting chlorine dioxide gas with a liquid.

A fluid control and gas delivery assembly and method for containing, receiving and storing hazardous fluids and for dispensing gas comprising a container, a fluid fill path, a gas dispensing path, a first shut-off valve, a pressure reducer, a fluid flow restrictor, a second shut-off valve and a fluid outlet connector. The first shut-off valve is positioned in said gas dispensing path upstream of a pressure reducer. A fluid flow restrictor downstream of the pressure reducer has a fluid flow restriction path configured to restrict the flow of the fluid delivered to the fluid flow restrictor at the delivery pressure to a maximum mass flow rate that is equal to or less than the allowable mass flow rate standard for the hazardous fluid. The second shut-off valve is positioned in said gas dispensing path downstream of said pressure reducer.
