The Solution dilution method has been discussed by theory analysis and experiment,at certain range,the solution dilution method is same as using standard samples recovery,it is a simple method to determine whether it has co-existing elements interference in use method of atomic absorption spectrophotometry.

This experiment chooses different solid particles dispersed in resin solution that make a different system,the role of surface adsorption and absorption system at the same time will have an impact on the conductivity after adding particles,trying to find a relationship between them.
