采用振荡平衡法对***酮在湖南第四纪红壤中的吸附行为进行研究,并探讨了吸附时间、浓度、温度、pH等因素对吸附的影响。结果表明,***酮在红壤上的吸附分为快速吸附和慢速吸附2个过程。快速吸附基本在8h内完成,当吸附时间延长至24h时,吸附量提高了20%。***酮初始浓度越大、吸附时间越长,在红壤上的最大吸附容量也越大;随着温度升高或pH值增大,***酮的吸附量降低。

Adsorption and desorption behaviors of a fungicide,triadimefon,in soil is an important factor governing bio-availability and persistency of the fungicide.In order to reveal adsorption behavior of triadimefon,in soil,the adsorption of triademefon in Quatemary red soil was conducted by batch sorption method,and influences of environmental factors were evaluated including consistency of solution,time,temperature and pH,respectively.The results indicated process of adsorption can be divided into fast-reacting course and slow-reacting course.The fast-reacting course was achieved in eight hours,but ...
