The elimination of salicylic acid using pulsed corona discharge in a multipin-plate reactor was investigated. It was found that salicylic acid removal increased with lower pH, initial concentration, and conductivity of the liquid.
Elimination of salicylic acid by pulsed corona discharge in a multipin-plate reactor was investigated. Corona discharge is an alternative technique that produces highly active species such as HO center dot that degrade salicylic acid. Salicylic acid was totally eliminated in 60 min of treatment with 200 stainless steel needles. Variables such as pH, initial concentration, conductivity, and Na2SO4 dosage were studied to elucidate their influence on salicylic acid elimination. Salicylic acid elimination increased with decreasing pH, initial concentration, and conductivity of the liquid.
