Flame atomic absorption spectrometry of chromium alloy steel,manganese

Determination of flame atomic absorption spectrometry of chromium alloy steel,manganese,second method is rapid,accurate,high sensitivity,good precision,the method is simple,and fully reflects the analytical tools of modern high-tech equipment.Alloy steel is extensively used,thus using atomic absorption spectrometry determination of chromium,manganese,can be detected quickly and effectively to achieve the purpose of needs.This method changes the chemical method is a long time past,steps and more,consume more than the ills reagents,chromium perchlorate solution is harmful and serious pollution of the environment.Done by the conditions of the experiment,the best instrument optimized test conditions.Elements of the interference of iron,nickel,chromium inhibit the absorption of sodium sulfate to do interference cancellation agent,the total elimination of the interference measurement data is stable and reliable.After the determination of standard samples,reproducible,small error rate of 99～102% satisfactory.
