正交试验在流动注射—氢化物—石墨炉原子吸收分光光度法中的应用

在生产和学科研究中经常需要做许多多因素的试验。如何安排多因素的实验是一个很值得研究的问题。若试验安排得好,则既可减少试验次数,避免试验的盲目性,又可得到好的效果;若试验安排得不好,则试验次数多,还不一定好。正交实验法(又称正交设计或正交法)是研究与处理多因素...

APPLICATION OF ORTHOGONAL TEST IN FLOW INJECTION-HYDRIDE-GRAPHITE ATOMIC ABSORPTION ANALYSIS

Adepting the orthogonal test to deal with the multiple factor experiments,we ean avoid the complex operation concerning about the single factor experiments of many times.In choosing the best experimental condition,it has many advantages,such as to reduce the number of times,to achieve good results,etc. This thesis generally tells about how to apply the orthogonal test to the flow injection and atomic absorption analysis to determine the element Bi(bismuth) and receives the most suitable length of the pipeline a(10cm),b(10cm),c(30cm) and the preheating time 35s as the experimental condition.
