摘要: 本文研究了银(Ⅰ)对a,a'-联吡啶与亚铁氰化钾反应的催化作用动力学测定微量银(Ⅰ)。测得银的催化反应为零级反应。在本文确定的条件,方法灵敏度为6.5×10-4微克/毫升,变动系数为0.072%,银的测定范围为0-3.5微克/40毫升。

Abstract: In this paper, estimation of trace silver(I) by catalytic kinetics of the reaction of silver(I) react with α,α'-dipyridyl and potassium ferro-cyanide was studied. It's showed, such catalytic reaction reacted in zero order, and under the conditions supported in this paper, sensibility of this method was 6.5× 10-4μg/ml and variable coefficient 0.072%. The range of silver estimated was 0-3.5μg/40ml.
