摘要
采用试验室内模拟试验的方法,研究不同pH的缓冲溶液和不同自然水体对氟磺隆水解的影响。实验结果表明,不同pH缓冲溶液和不同自然水体对氟磺隆水解速率均有不同程度的影响。在碱性条件下氟磺隆的水解速率最快,半衰期为0.2 d,酸性条件下次之,半衰期为6.0 d,在中性条件下水解较慢,半衰期为15.7 d,而在不同自然水体中氟磺隆的降解速率为:伊通河水>稻田水>青湖水>蒸馏水。
This experiment was based on indoor cultivated method. The purpose of this study was to research on the influ- ences of elucidated solutions of various pH levels and different natural waters on the hydrolysis of prosulfuron. The results showed that prosulfuron hydrolysis varies in different PH buffer aqua and different natural waters. The rate was fastest in alkaline condi- tions with the half life as 0. 2d, less fast in acidic conditions with the half life as 15.7d, and slow in neutral condition with the half life as 6. 0d . While the degradation rates of Prosulfuron in different natural waters was Yitong River 〉 paddy water 〉 Green Lake 〉 distilled water.
