Abstract
A method is disclosed for stabilizing glutaraldehyde in aqueous systems is disclosed. The method of the invention comprises the addition of an oxidizer to the aqueous system so as to prevent the undesired conversion of glutaraldehyde to non-biocidal products.
Claims16
A method for stabilizing glutaraldehyde in a kaolin slurry containing an effective amount of glutaraldehyde to substantially kill or inhibit the growth of microorganisms in said slurry, which comprises providing an oxidizing agent to the kaolin slurry in an amount at least sufficient to substantially prevent the reaction of glutaraldehyde to delta-valerolactone.
In a method for stabilizing glutaraldehyde in a mineral slurry containing an effective amount of glutaraldehyde to substantially kill or inhibit the growth of microorganisms in said slurry, which comprises providing an oxidizing agent to the mineral slurry in an amount at least sufficient to substantially prevent the reaction of glutaraldehyde to delta-valerolactone:
- the improvement wherein the oxidizing agent is provided to the slurry prior to the addition of glutaraldehyde.
In a method for stabilizing glutaraldehyde in a kaolin slurry containing an effective amount of glutaraldehyde to substantially kill or inhibit the growth of microorganisms in said slurry, which comprises providing hydrogen peroxide to the slurry to stabilize the glutaraldehyde:
- the improvement wherein the hydrogen peroxide is allowed to disseminate throughout the slurry before the addition of the glutaraldehyde such that at least 90% of the glutaraldehyde in the slurry remains seven days after providing the hydrogen peroxide and glutaraldehyde to the slurry.
