在X 线片的定影液中,含有一定量的银离子,人们可以用各种方法提取。电解提银法是用正负两个电极插入定影液中,电解器的直流电通电后,由于电场作用,银离子即在负极板上堆积起来,经收集后进行冶练提纯。电解器主要由一个降压变电器将220伏特的电压降至12伏左右,将电流通过可变电阻,调整至300毫安培左右,通过半导体二极管,进行桥式全波整流,使交流电变为直流电。变压器输的正极端接至40×20×
X-ray film in the fixing solution, contains a certain amount of silver ions, people can use a variety of extraction methods. Electrolytic silver extraction method is to use two positive and negative electrodes into the fixing solution, the DC power of the electrolyzer, due to the electric field, silver ions that are stacked on the negative plate, after purification by purification. The electrolyzer mainly by a step-down transformer 220 volts down to about 12 volts, the current through the variable resistor, adjusted to about 300 milliamperes, through the semiconductor diode bridge full-wave rectification, the AC into direct current . The positive terminal of the transformer is terminated to 40 × 20 ×
