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.

本论文在回顾螯合吸附材料的合成及其在贵金属的离线和流动注射在线预浓集分离发展状况的基础上，首次合成了含罗丹宁、2-巯基嘧啶、2-巯基噻唑啉和异二苯基硫脲等四种以硅胶为载体的螯合吸附剂，并用于银、金、钯和铂的流动注射微填充柱在线预浓集分离、火焰原子吸收光谱分析。

The stabilities of the extract from sanguisorba under different pH, light, heat, ultraviolet ray, oxidant, reducing agent and additive agents were studied. It was indicated the products could widely used in the condition of weak acid or neutral, while they were not stable to heat and light, so they should be used without light and at low temperature. The products had a strong ability to withstand ultraviolet ray. They could easily be oxidized and degraded by oxidant while they were not easily affected by reducing agent and were almost not affected by additive agents. The extract from the stem of sanguisorba was analyzed by UV and FTIR, showing that the structures of the active components were not changed during ultrasonic wave extracting.

研究了pH值、光、热、紫外线、氧化剂、还原剂以及添加剂对地榆提取物稳定性的影响，结果表明地榆提取物适合弱酸或中性条件下使用，使用范围比较广；但对光热稳定性较差，适合在避光低温的环境；具有很强的抗紫外线能力；氧化剂对地榆提取物稳定性影响较大，会加速其降解，还原剂对地榆提取物影响不大；其他添加剂对其稳定性几乎没有影响；并通过UV和FTIR光谱分析，超声波浸提没有对地榆根茎中有效成分的结构发生改变。

Samples' Raman spectra were measured at 23℃, 230℃,and signation of these spectra was discussed in the paper.
