The experiment was in progress in dyadic foam of intermittence flotation tower,to the positive ion type,the negative ion type,type and amphiprotic type,etc.

结果：泡沫浮选法去除废水中铬离子的表面活性剂，阳离子型和非离子型表面活性剂效果最差，阴离子表面活性剂效果最好。

The novel complex (1) in which both benzylic nitrogens and heteroaromatic ones to the same metal ion with the rigid ligand imposed by the large heteroaromatic moiety first time was synthesized; a 2: 1 (ligand: metal ions) type complex which has steric resistance and strong thermochemical driving force was obtained. The crystal structures of characteristic ligand (LA4) and complexes (4, 7, 10), in which one cell includes two moieties: there exist minute difference in coordinated bonds and angles despite the same metal ions with the same ligand, were obtained. It shows that several stable conformation in one complex cell.

首次合成了含邻菲罗啉的具有较大刚性的四氮配体中四个氮原子全部与同一金属离子配位的配合物的晶体结构；得到了一个在空间上存在位阻作用的配体与金属离子2：1结构的晶体；解析了具有特色的一个配体（LA4）和三个配合物（4、7和10）的晶体结构，其中的配体与金属离子的配位作用显示出细微的差异，表明在同一金属配合物的晶胞中，可以同时存在着多个稳定的构象。

首先，我们对脲嘧啶与锌离子以及水合锌离子的耦合情况进行了讨论。

It is found that in the medium of H3PO4,the fading reaction of Methyl violet is quickened by IO3-with the presence of micro iodine. The fading of methyl violet is found to be directly proportional to the amount of iodinate,and linear range is 0～2 μg/ml.

在磷酸介质中，微量碘离子与碘酸钾氧化反应能催化甲基紫褪色，而且褪色程度与碘离子的量有关，最大吸收波长在575nm，在0～2μg/ml范围内呈线性关系。

Compared with the exponent function, the power function can be more suitable for fitting the change of chemicals concentrations in runoff under unsaturated conditions from the loess slope,as well as,the mass loss of potassium and bromine in runoff,but not for initial phase. The study offered a reference for developing the model of soil nutrient in runoff transport of the loess slope.

同时利用两种类型描述径流养分浓度模型对实测资料进行分析，结果显示与指数函数模型相比较，采用幂函数模型能够较好地模拟黄土坡面非饱和条件下径流溶质浓度变化过程，同时幂函数模型也能够较好地描述径流中钾离子和溴离子的质量变化过程，为进一步完善黄土坡面径流养分迁移模拟模型提供了参考。
