水络合物

A new fluorescence quenched method has been found for determination of trace of gold based on the formation of nonfluorescent ternary complex Au- TBT -APDC.The composition ratio of Au to ligandi is 1:2:2.Under the optimum conditions,the linear range of the calibration curve is from 0 to 160ng Au/ml.

本文研究了在聚乙烯醇存在下，金与曙红、吡咯啶二硫代氨基甲酸形成三元络合物的合宜条件，并据此建立了水相荧光熄灭测定痕量金的新方法。

Ti〓 ion and triethanolamine may be combined together to form a complex which is dissolved in water at normal temperature.The hydrolysis of Ti〓 ion is controlled by the formation of the complex.

Ti〓离子和三乙醇胺可形成常温下较为稳定的水溶性络合物，从而避免了Ti〓离子的直接迅速水解。

The result indicated that MgO and α- methacrylic acid can together thicken epoxy, and the speed of thickening epoxy become quickly with the increasing content of MgO; when the ratio of MgO and α- methacrylic acid is 3:1, thickening epoxy have a better effect; the thickening mechanism: the terminal corboxyl group of α- methacrylic acid react with MgO, and it accompany with large numbers of heat, the heat can accelerate the reaction between the terminal corboxyl group with the secondary hydroxyl groups of epoxy, intermolecular hydrogen bonding which the water of above-mentioned formation result in and complex compound which format the metal atoms and carbonyl group complexing collective increase the viscosity of epoxy resin.

结果表明：MgO和α－甲基丙烯酸配合可增稠环氧树脂，随着MgO加入量的增加，环氧树脂增稠的速度加快；MgO与α－甲基丙烯酸为3：1时，增稠环氧树脂的效果较好；推测环氧树脂的增稠机理是α－甲基丙烯酸中的端羧基与氧化镁反应，放出热量促使其端羧基与环氧树脂中的仲羟基反应，上述反应生成水产生的氢键和羰基与氧化镁中的金属原子形成络合物共同导致环氧树脂的粘度增加。

Firstly, there exists complex compounds based on hydrogen bond in DMSO aqueous solution.

并用CCl_4变换浓度的方法，验证了DMSO与水混合时产生的氢键络合物对S=O双键光谱的影响。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。
