本文报导了蒙脱石、高岭石和有机质胡敏酸以及浙江省有代表性的小粉土、海涂土、青紫泥对三环唑的吸附、解吸和pH值的影响,试验结果表明,它们的吸附都符合Freundlich等温吸附经验方程,前三者等温线分别属S-型,L-型和C-型,三种土壤都属C-型,蒙脱石、高岭石和胡敏酸对三环唑的吸附能力均较土壤强得多,三种土壤的吸附性能以涂土最差,小粉土和青紫泥相差不大,pH值对吸附和解吸影响很大;pH=2时,吸附量最大,解吸率最小,pH值变化时高岭石吸附、解吸影响最大,随pH值增大,对三环唑的吸附量减少,解吸率增加。
In this paper, the adsorption, desorption and pH of montmorillonite, kaolinite and organic humic acid as well as representative small silt, tartar and purplish mud in Zhejiang Province are reported. The results show that their Adsorption are in line with Freundlich isotherm adsorption empirical equation, the first three isotherms were S-type, L- and C-type soil, three kinds of soil are C-type, montmorillonite, kaolinite and humic acid on the tricyclic The adsorption capacity of azole was much stronger than that of soil. The adsorption properties of the three soils were the least, the small silt and the purple clay had little difference, and the pH had a great influence on the adsorption and desorption. At pH = 2, the adsorption capacity Maximum, the desorption rate is the smallest, kaolinite adsorption and desorption when the pH value changes the most, with the increase of pH, the adsorption amount of tricyclazole decreases, the desorption rate increases.
