Surface barrier-discharge plasma treatment of aqueous phenol solutions

The rate of phenol degradation in aqueous solution was shown to depend on p henol concentration, time of discharge treatment of the liquid, contact tim e of the carrier gas with the liquid, and power input to the discharge. The maximum degree of phenol degradation in aqueous solution is 73%. Main orga nic compounds produced by degradation are formaldehyde and monocarboxylic a cids. In addition, ozone and nitrogen oxides were detected in the gas phase , and ozone and ammonium, nitrite, and nitrate ions were found in the liqui d phase.
