差式分光光度法测定钢铁中高含量的镍

High—Content Ni In Iron And Steel Determined By Differential Spectrophometry

本文介绍了差式分光光度法测定高含量镍的方法。此法在丁二肟比色测定低含量镍的基础上,选用一定浓度的镍离子发色液作参比浴液,在一定试验条件下用差式比色。此法周期较短、成本较低,而且可靠性、重现性也好,灵敏度准确度均合符要求。

High-Content Ni determined by differential spectropho tometry is reportedin this paper. Based on dibuty loxime determining Lowcontent Ni and certainconditions of test, this mothod applies the differential colormetry to colorsolution with given concentration Ni ion as reference solution. This measurementfor high-content Ni is suitable for a number of samples anaysis in factory bec-ause of shorter period, inexpensive cost, good repeatity, higher sensibility andadeacy accorded with reguiorments conserned.
