电位溶出分析具有灵敏度高,重现性好,设备又较为简单等优点。尤其它允许大量有机物质和电活性物质存在,对样品的前处理简单,为其它方法所不及的。我们将Triton x-100非离子型表面活性剂应用于电位溶出分析,发现它可以明显地提高分析的灵敏度和重现性,改善溶出峰形。 Potential dissolution analysis with high sensitivity, good reproducibility, the device is relatively simple and so on. In particular, it allows a large amount of organic and electroactive substances to be present, and the pretreatment of the sample is simple and not possible with other methods. We applied Triton x-100 non-ionic surfactant to potentiometric stripping analysis and found that it significantly improves the sensitivity and reproducibility of the assay and improves peak dissolution.
