【摘要】：采用熱活化過硫酸鹽法,考察了過硫酸鹽濃度、溫度、水土比和初始pH對(duì)柴油污染土壤氧化修復(fù)的影響,并分析了其動(dòng)力學(xué)和熱力學(xué)參數(shù)。結(jié)果表明,當(dāng)Na2S2O8摩爾濃度為0.8mmol/g、溫度為70℃、水土比為2.0mL/g、初始pH為11.00時(shí),反應(yīng)72h后的柴油降解率最高,達(dá)到77.85%。動(dòng)力學(xué)和熱力學(xué)分析表明,熱活化過硫酸鹽氧化降解柴油過程為自發(fā)、吸熱、熵增的過程,表觀活化能為-80.73kJ/mol。
[Abstract]:The effects of persulfate concentration, temperature, water / soil ratio and initial pH on oxidation and remediation of diesel-contaminated soil were investigated by thermal activated persulfate method. The kinetic and thermodynamic parameters were analyzed. When the molar concentration of Na2S2O8 is 0.8 mmol / g, the temperature is 70 鈩，
