水合氢离子

Structures of Na~+-AD ion-complexes with 1 or 2 H2O molecules were obtained. It was found that H2O can bond with Na~+ in the structure of Na~+-AD to form Na-O van der Waals bond. H2O molecule can also bond with N or O atoms in AD moiety to form H-bonds as N-H…Ow or O…Hw-Ow. The former process takes place more easily. The most stable structures of Na~+-AD ion-complexes with 1 and 2 H2O molecules are W-C7AB and 2W-C7AB, respectively.αB conformer of Na~+-AD can not exist in the presence of 2 H2O molecules.

研究发现水分子可以结合在Na~+-AD络合离子中的Na~+附近形成Na-OW范德华键，也可以与Na~+-AD络合离子骨架结构中电负性较强的N或O原子结合形成N-H…OW或O…HW-OW氢键，相对而言，水分子更容易结合在Na~+-AD络合离子中的Na~+位置，Na~+-AD最稳定的带1个或2个水分子的结构分别为W-C7AB和2W-C7AB，Na~+-AD络合离子的αB构象在2分子水存在的情况下完全消失。

As the RE ions concentration in groundwater increases or the surface sites on Mn-Fe oxide become saturated, RE ions may sorb via surface precipitation, then surface precipitation become the dominant sorption mechanism.

当离子浓度低时，形成表面络合物是占统治地位的吸附机制；当氧化物/水体系中离子浓度大时，金属离子除在表面形成表面络合物外，也可能形成表面氢氧化物沉淀，直到氧化物表面吸附点位被全部占满，这时表面沉淀则变成主要的吸附机制。

Single component and multi\|component of iron system colloidal catalyst \Ali\|Bu\-3CH\-2CHCH\-2Cl\ were mixed by different ratios in hydrogenated gasoline medium at 25℃.This paper studied the relationship between the nonaqueous systematic electroconductivity and the concentration of catalyst components.In combination with Tyndall effect,polymerization experimental results,Ali\|Bu\-3 existed in associated state and dissociated into ionpair.The reaction between Ali\|Bu\-3 and Fenaph\-2 was the main reaction which formed colloidal core.Ali\|Bu\-3 reacted on CH\-2CHCH\-2Cl and Ali\|Bu\-2Cl was yielded which joined the formation of active center on the surface of colloidal core.The excessive Ali\|Bu\-3 was dissociated into ionpair which formed double electrode layer,and the double electrode layer kept the colloidal particles relatively stable.
