医院放射科都愿在废定影液中回收白银,但市售的白银回收器价格比较昂贵,有些产品可靠性较差。笔者介绍一种简单可靠,易于监视、利用业余品仅花10元钱就可制成的白银回收器供同道者参考。 附图,电路原理 4支二极管组成桥式整流电路,W、R_1、R_2及三极管组成稳流电路,电源的负极接不锈钢板电极,三极管集电极接炭素电极,把这两个电极插入定影液中,该电路接通,定影液被电解,这时带正 Hospital radiology are willing to waste silver in the fixer solution, but the commercially available silver collector prices are more expensive, and some products less reliable. The author introduces a simple and reliable, easy to monitor, use of amateur products can only be made of silver recycler for the fellow who reference. Figure 4, the bridge circuit composed of four diodes, W, R_1, R_2 and transistor constitute a steady current circuit, the negative electrode of the power supply stainless steel plate electrode, the collector electrode connected to the carbon electrode, the two electrodes into the fixing solution , The circuit is switched on, the fixing solution is electrolyzed, then with a positive
