一、引言到目前为止,据了解大多数化验室分析钢中夹杂氧不外乎有比色法和重量法两种。此色法灵敏度高,可达0.0001%;药剂用量少;分析速度快。但此法需具备灵敏度较高的比色计,否则,会造成很大偏差。重量法是较通用的一种方法,但还存在着许多缺点,如试剂用量较多;操作步骤繁杂;倘若酸度控制不稳定时,结果容易偏高,用于微量分析时更加无能为力。虽然光谱分析尚未达到尽善尽美的程度,但还是显现 I. Introduction So far, it is understood that most laboratory analysis of steel in the mixed oxygen is nothing more than colorimetric and gravimetric two. This method of color sensitivity, up to 0.0001%; ​​less dosage; analysis speed. However, this method requires a more sensitive colorimeter, otherwise it will cause a great deviation. Gravimetric method is a more common method, but there are still many shortcomings, such as reagent dosage is more; complex steps; if the acidity instability control, the results tend to be high, more powerless for microanalysis. Although spectral analysis has not yet reached the perfect level, but still apparent
