摘要

以Fe(SCN)3-NaNO2为本底反应的碘催化比色测定方法灵敏度高,检出限达10-8,线性范围宽,精密度、准确度高,分析简便、快速。本方法在油气化学勘探应用中取得了良好的效果。

Abstract

The method of iodine catalytic colorimetric determination who takes Fe(SCN)3-NaNO2 as a background reaction has high sensitivity(detection limit up to 10-8),wide linear ranges,and high precision and accuracy.The analysis using this method is simple and rapid,and has obtained good effects in its application to geochemical prospecting for hydrocarbon.
