环炉分析法由于它简单、迅速、经济、灵敏,因而得到了迅速的发展。目前已与其他分析方法结合使用,更显示了它的优点。但该法的分离,通常是基于一部分离子被沉淀剂沉积固定于原点,而将不沉淀的离子借滤纸毛细管效应,以适当的溶剂洗出使成环带,这样在沉淀的表面上不免要吸附一些被分离的离子。实验证明,虽经多次洗涤亦难完全除去,此为其不足之处。我们将反相纸上分配层析法与环炉法结合使用,即用反相层析法分离而以环炉浓集,既可克服
Ring furnace analysis has been rapidly developed because of its simplicity, speed, economy and sensitivity. It has been combined with other analytical methods to show its advantages. However, the separation of the method is usually based on a part of the deposition of ions by precipitation agent fixed at the origin, and the non-precipitation of ions by filter paper capillary effect, with a suitable solvent wash out into the ring, so that the surface of the precipitate inevitably adsorption Some ions are separated. Experiments show that although after repeated washing is difficult to completely remove, this is its inadequacies. We will reverse the paper on the distribution chromatography method combined with the ring furnace, that is separated by reverse phase chromatography and ring furnace concentration, can overcome
