测定地质样品中的微量铂,令人满意的方法比较少,这些方法大都有分析步骤冗长、成本高和污染环境等问题。近年来利用有机萃取剂负载于聚氨酯泡沫的隔膜上进行吸附金属离子的研究有不少的报导,但未见有利用泡沫塑料富集铂的应用文章。本文研究了本实验室合成的海绵状开孔型的叔胺泡沫塑料吸附铂离子的行为,并就吸附的介质、酸度,以及四十余种离子对吸附的影响进行了实验,确定了富集地质样品中铂的最
Determination of traces of platinum in geological samples, the satisfactory method is relatively small, most of these methods are lengthy analysis steps, high cost and environmental pollution problems. In recent years, the use of organic extractant on the polyurethane foam membrane adsorbed metal ions have been reported on the study, but there is no use of foam-rich platinum application article. In this paper, we studied the adsorption behavior of platinum ions on sponge-like open-cell type tertiary amine foams synthesized in this laboratory. The adsorption media, acidity, and the influence of more than 40 kinds of ions on the adsorption were investigated. Geological samples in the most platinum
