摘要
光降解是许多药物类污染物在地表水中的重要去除方式。在UV-vis照射下,研究水体中的无机离子对布洛芬光降解的影响。结果表明,在反应液中添加金属离子和碳酸氢根时,布洛芬的光降解都很好的符合准一级动力学。金属阳离子和HCO-3均可抑制布洛芬的光降解,且抑制率随添加浓度的增大而增大。
Photodegradation is likely to be an important loss mechanism for many pharmaceutical pollutants in surface water. The effects of inorganic ions on ibuprofen（ IBP） photolysis in aqueous media are studied under UV- vis irradiation. The results show that the degradation of ibuprofen complies with the pseudo- first- order kinetics model when metal cations or bicarbonate is added individually into the solution. Metal cations and bicarbonateall can inhibit the photodegradation of ibuprofen,and the inhibition rate increases with the increase of concentration.
