In order to improve the electro-catalytic activity of platinum based catalyst to methanol oxidation, in this thesis, firstly prepare heteropoly acid modified Pt/GC electrode with different concentration by cyclic voltammetry method, and then test the cyclic voltammetry curves individually in vitriolic and methanol solution. The study shows the best concentration for both phosphomolybdic acid and phosphotungstic acid is 1×10~(-3)mol/L. And find the more heteropoly acid modified on electrode, the lower peak-up potential towards methanol because of the existence of oxygenous species.

为了改善铂基催化剂氧化甲醇的催化活性，本论文首先通过循环伏安扫描法制备了不同浓度磷钼酸和磷钨酸修饰的Pt/GC电极，通过研究Pt/GC电极在修饰前后在硫酸溶液中及含甲醇的硫酸溶液中的循环伏安行为发现，磷钼酸和磷钨酸均能在PtRu/C电极上发生氧化还原反应，而且杂多酸修饰浓度对Pt/GC电极氧化甲醇的催化活性有很大影响。

The dogs were administrated with carboplatin at the dosage of 16.5mg/kg intravenously, intra-arterially or retroperitoneally. The blood samples were taken at 0, 5, 15 minutes, and 0.5, 1, 2, 4, 8, 24 and 72 hours after instillation. The competent platinum concentrations were measured with high-performance liquid chromatography. Then the pharmacokinetic parameters were calculated and analysed.

随机将18只雌性家犬分为3组，分别经静脉，动脉及腹膜后推注卡铂(16.5 mg/kg)，然后于给药后的0、5、15分钟，0.5、1、2、4、8、24、72小时取静脉血，用高效液相色谱法测定血浆活性铂的浓度，计算和比较不同给药方式下卡铂的药代动力学参数。

The literature about the synthesis of the ion exchange and chelating adsorbents used in the off-line separation and preconcentration of the noble metals and the development of the on-line microcolumn separation and preconcentration of the noble metals were reviewed. Four silica gel-based adsorbents with rhodanine, 2-mercaptopyrimidine, 2-mercaptothiazoline and isophenylthiourea as the functional groups were first synthesized and applied to the on-line separation and preconcentration of silver, gold, palladium and platinum for their FAAS determination.
