| Abstract: | The silica gel microspheres encapsulated by salicylic acid functionalized polystyrene were synthesized and used to prepare microcolumn,the breakthrough and elution curve were studied, and it was used to separate and preconcentrate of Ag（I）,the influencing factors were investigated and optimized. The linear range of detecting Ag（I） was 0. 020-0.50μg/mL,the method has been applied to the determination of trace silver in water samples. |
