The Preparation And Appliance Of Silver Resin

According to the principle of lower consumption, lower pollution and higher yield, the technique theory of the preparation and application of silver resin was discussed. Firstly we studied the technology of the preparation of silver resin. This method was that hydrogen-type strong acid cation exchange resin reacted with AgNO3 prepared from the waste photographic fixing liquid. The effect of temperature and time were also discussed. And we achieved the best condition of the preparation. And we also tested the disinfect effect of silver resin .Its ratio was above 99% which confirmed that the disinfect of silver resin was better. Dealing with the seawater with silver resin was elementarily discussed. This paper was not only studied the leak of silver but also came up with the resolution.This paper discussed the regeneration process of silver resin. Comparing with the conventional technology, the paper applied a new kind of technology. Both the effect of the ratio of combined resin and the effect of time was also discussed. And we achieved the best regeneration condition of silver resin.
