| 摘 要： | 对偏二甲肼在红壤土和黄棕壤土中的吸附及降解进行了研究。通过对不同浓度的偏二甲肼在这两种土壤中的吸附的研究,用改进的平衡法给出了偏二甲肼在这两种土壤中的吸附等温线,得出了它们的吸附常数。通过对偏二甲肼降解产生的中间产物甲醛的初步研究,得到偏二甲肼在两种土壤中降解产生的甲醛浓度随时间的变化趋势,并对测得结果进行了讨论。

| Abstract: | Adsorption and decomposition of unsymmetrical dimethyl hydrazine (UDMH) in red soil and yellow-brown soil are performed in the present study. The adsorption curves and adsorption isotherms of UDMH in the two soils are obtained using an improved equilibrium method, and the adsorption coefficients were calculated, through the studies of the adsorption of UDMH in different concentrations. It has been found that formaldehyde was a degradation product of UDMH in the two soils and obtained the changing trends with time for the formaldehyde. |
