摘要:
研究了Fe(III)与二苯胺磺酸钠的显色反应,建立了测定Fe(III)的光度分析方法.该法测定线性范围为0~7 μg·mL-1,检出限为0.2 μg·mL-1.用于水样中Fe(III)的测定,回收率在109.0%~101.0%,相对标准偏差小于5%,结果较满意.
Abstract:
The article has researched the reaction of mixing iron (III) and diphenylamine sulfonate up. It has been found that absorbance of the production is in line with Beris law when the concentration of diphenylamine sulfonate varies from 0~7 μg·mL-1. The minimum concentration detected is 0.21 μg·mL-1.To determine the quantity of iron (Ⅲ) of the sample of water with this method, the recoverie is 109.0%-101.0% and the relative meansquare is less than 5%. The result is satisfying.
