  ion-
Besides the hydrophobic interaction provided by nonpolar dodecyl, DPZ also has dipolar interaction, ion-exchange or electrostatic repellent interaction provided by the free phosphonic group and amino group at different conditions.
      
The ion-exchanger LiAlTiO4 of spinel type was prepared by the common precipitation/hydrothermal crystallization method, and was acid-modified.
      
Its ion-exchange properties for alkali ions such as saturation capacity of exchange, distribution coefficient and pH titration curve were determined.
      
This paper investigates the enhancement of Langmuir and ion-acoustic wave and the acceleration of the electron in collisionless plasma, in the presence of an external transverse field.
      
The results show that Langmuir and ion-acoustic wave are enhanced and the charged particles can be accelerated by the coupling of wave-wave.

The origin of the system of bands around 2482 A.U. observed in a mercury lamp has been given evidence as due to mercury molecular ion. Quantitative determination of the intensity variations as a function of pressure and current of the 2482 bands and other band of neutral molecules, shows marked difference between 2482 bands and other bands. All the differences can only be explained on the basis of an ionic origin of the 2482 bands. The excited state of the molecular ion that emits 2482 bands is given...

The origin of the system of bands around 2482 A.U. observed in a mercury lamp has been given evidence as due to mercury molecular ion. Quantitative determination of the intensity variations as a function of pressure and current of the 2482 bands and other band of neutral molecules, shows marked difference between 2482 bands and other bands. All the differences can only be explained on the basis of an ionic origin of the 2482 bands. The excited state of the molecular ion that emits 2482 bands is given evidence as that state resulted from a combination of a normal atomic ion and a neutral atom at the 3P1 excited state.

水银分子在2482A.U.左右有组光带,是水银分子伊洪的还是水银分子的这问题,我们用光谱强度的测量法解决了。将供作光源的通电管内的电流或水银气压依次的改变,我们发现2482A.U.光带的强度的改变和旁的已知的分子光带绝然不同。那些不同之点,只要引用“分子伊洪是2482光带的原主”这说法,就都明白了我们更进一步问放出2482光带的是那个高能力阶位理论和实验的结果指示出一个在最低能力阶位的原子伊洪(Hg~+)和一个在3P_1能力阶位的原子所结合成的分子伊洪是能放2482光带的高能力阶位。

Von Knorre first suggested the use of benzidine and o-tolidine for the determination of tungsten. With the latter reagent, he succeeded also in separat- ing tungstate from phosphate. Later on, o-dianisidine and vanillylidene benzidine have been proposed as precipitants for tungstate. The optimum pH ranges for the quantitative precipitation of tungstate by means of these precipitants and tetraminodiphenyl, which have not yet been found in the literature, are: benzidine pH: 2.0-5.5 o-tolidine 2.9-4.7 o-dianisidine...

The optimum pH ranges for the quantitative precipitation of tungstate by means of these precipitants and tetraminodiphenyl, which have not yet been found in the literature, are: benzidine pH: 2.0-5.5 o-tolidine 2.9-4.7 o-dianisidine 2.0-4.1 vanillylidene benzidine 1.7-3.9 tetraminodiphenyl 1.7-4.8 The effect of introducing various groups into the benzidine molecule upon the tungsten precipitating property is not profound. The relation between quantitative precipitation of tungstate with benzidine and the product of concentrations of both constituents before precipitation Was studied. It is found that quantitative precipitation of tungstate ions Can be realized only when the product of concentrations of reactants before precipitation is equal to or greater than 0.8 × 10~(-5), and the moles of benzidine added must be at least equal to that of tungstate. The gravimetlic determination of tungsten by means of o-tolidine may be applied to samples containing as low as 10 mg of rungsten trioxide in 200 ml solution, if an absolute error of 0. 5 mg can be tolelxted. For larger quantities of tungsten present in sample, the absolute errors amount to only 0.1-0.2 mg. Tetraminodiphenyl may be used as a tungsten precipitant, but no advantage over benzidine Wan found in our present studies.

1.用二胺聯苯及其數種衍生物沉澱鎢酸根時,其適宜的pH範圍如下:[4,4′]二胺聯苯 pH:2.0-5.5[3,3′]二甲基[4,4′]二胺聯苯 2.9-4.7[3,3′]二甲氧基[4,4′]二胺聯苯 2.0-4.1[4]對胺聯苯氮甲烯[2]甲苯酚 1.7-3.9[3,4,3′,4′]四胺聯苯 1.7-4.8 2.用[4,4′]二胺聯苯作沉澱劑時,二胺聯苯和鎢酸根在沉澱前的濃度之乘積與後者沉澱完全與否的關係,曾加研究。 3.用[3,3′]二甲基[4,4′]二胺聯苯作沉澱劑時,能测定低至10毫克的三氧化鎢。

Vanillalrhodanine was found to be an excellent reagent for silver ions. Its 0.2 percent solution in acetone gives a brownish violet precipitate with silver ions in ammoniacal solution. Limit of identification: 0.01γ. Concen- tration limit: 1∶5,000,000. Merecric and merourous ions give same reactions, but they can be removed by the addition of aqueous ammonia and the test is to be carried out in the filtrate. Ferric ions, when present in high concentra- tions, interfere the observation...

3甲氧基4羥基亞苄羅丹寧可以用作銀離子的斑點試劑。其千分之二丙酮溶液與銀離子在含氨溶液中生成棕紫色沈澱。鑑定限度為0.01_γ,濃度界限爲1∶5,000,000。普通離子除汞外皆不干擾。鐵鹽在濃度高時,才妨碍銀的鑑定。
