Sonochemical Treatment To Remove Hydrazines From Water

A sonochemical treatment has been proposed for removing hydrazine contaminants from water. The basis of the proposal is a conjecture that the sonochemical effect in water containing hydrazines would cause the hydrazines and some of the water to decompose, forming relatively innocuous products like nitrogen, ammonia, and derivatives of ammonia. On a large scale, this treatment could be incorporated into processes for remediation of industrial wastewater streams. On a smaller scale, this treatment could be effected by portable equipment that could be brought to locations where water contaminated by hydrazines has been spilled; examples of such locations include industrial chemical processing sites and spacecraft-launching sites, where hydrazines are used as hypergolic fuels.
