摘要
研究了直接用稀硝酸溶液浸渍胶片制取硝酸银 ,考察了浸银的最佳工艺条件。银的浸出率可达 10 0% ,制备的硝酸银纯度可达 99.5 %以上。方法简单可行 ,同时碱解聚酯废料制取对苯二甲酸 (PTA) ,PTA的纯度可达 96 %以上 。
Waste file was imprognated with dilute nitric acid to prepare silver nitrate.The optimum experimental conditions were tested.The diffusion rate of silver was 100%, and the purity of silver nitrate was up to 99.5%. The waste hydrolysis polyester was used as material to prepare terephthalic acid which the purity was 96 %.
