用光度比色法测定水中痕量银

DETERMINATION OF TRACE SILVER IN WATER SAMPLE BY CATALYTIC KINETIC SPECTOPHOTOMETRY

对源水和饮用水中所含痕量银 (小于 4μg L)的检测 ,可以根据银离子的催化作用 ,采用催化动力 -光度比色法进行测定 ,既能降低检测成本又能保证检测精度的要求。

Based on the catalysis of silver (Ⅰ) a catalytic spectophotomeric method for the determination of trace silver(<4μg/L) in raw water and drinking water has been studied. The method improves the precision of determination and reduces the cost of determination.
