在玻璃纤维生产中 Pt Rh Au 合金漏板长期处于高温状态,部份挥发渗入耐火砖及玻璃渣中,或者漏板被污染毁坏而不能继续使用,因此必须制定合理的回收工艺。作者将试样经王水溶解得 Pt Rh Au 钠盐溶液。如果直接采用同 Pt Rh_7合金通常所用的离子交换分离贱金属的提纯工艺,则甚简便。但结果发现其中的金被树脂还原吸附,导致树脂不能用一般方法再生,也影响了离子交换树脂本身的交换容量,降低提纯效
In the glass fiber production Pt Rh Au alloy leak plate in the long-term high temperature state, some volatile infiltration of refractory bricks and glass slag, or the drain plate is contaminated and can not continue to use, and therefore must develop a reasonable recovery process. The sample will be dissolved in aqua regia Pt Rh Au sodium salt solution. It is even easier if the purification process is used to separate base metals by ion exchange as is commonly done with Pt Rh-7 alloys. However, it was found that the gold was adsorbed by the resin, resulting in the resin can not be regenerated by ordinary methods, but also affect the exchange capacity of the ion exchange resin itself, reducing the purification effect
