摘要

对尿素在肯尼亚Eburru土壤上的耗散和吸附进行了动力学研究，结果表明，在平衡24小时内，35.00%的尿素被吸附在Eburru土壤基质纳米孔中。通过XRD、FTIR和SEM表征进一步证实了负载土样品中尿素分子的存在。Eburru负载土壤样品的尿素控释率在水中为82.8%，在基库尤土壤中为74.2%。

Dissipation and Sorption of Urea on Eburru Soils in Kenya

Dissipation and sorption of urea on Eburru soils in Kenya was done using kinetic studies which indicated that 35.00% of urea was adsorbed in the Eburru soil matrix nanopores within an equilibration of 24 hours. The presence of urea molecules in the loaded soil samples was further confirmed by XRD, FTIR and SEM characterization. Controlled urea release behavior of Eburru loaded soil samples was also determined to be 82.8% in water and 74.2% in Kikuyu soil.
