|
This study was conducted to investigate the effect of ozonated water and ozonated water+hydrogen peroxide treatment of residual procymidone in perilla leaf containing 20 mg/L procymidone. Samples was treated with ozonated water containing 1.0, 2.0 and 3.0 mg ozone and hydrogen peroxide water containing 1.0, 2.0 and 3.0 mg hydrogen peroxide in pH 5, 7 and 9, respectively, at . Procymidone removal rate was 26.5% in 7 days at and optimum condition of procymidone removal was the case of treating with ozonated water containing 2.0 mg and pH 9. As the result procymidone removal rate was about 96.5%. In this case of adding hydrogen peroxide, optimum condition of procymidone removal was . However, procymidone was nearly removed with the treatment of hydrogen peroxide water only.
