Method for determining la element in aluminum wire by spectrometer

Abstract

The invention discloses a method for determination of La element in an aluminum wire / aluminum based alloy with a spectrometer. The method includes the steps of: (1) setting the analysis conditions ofa to-be-determined sample: adopting a max type X-ray fluorescence spectrometer; (2) selection of standard samples: selecting multiple groups of aluminum based alloy standard samples and the percent content range; (3) drawing a work curve diagram; (4) preparing the to-be-determined sample and standard samples; and (5) calculating the content of La element in the aluminum based alloy. The method provided by the invention has the beneficial effects that: a series of standard samples are employed to draw the work curve, without destroying the sample, the content of La element in wide range aluminum wire / aluminum based alloy / high-purity aluminum alloy can be determined accurately and rapidly; the analysis result is accurate and reliable, and meets the rapid and accurate demands of enterprises for detection of chemical test data; the operation is simple and the reproducibility is good; and the method also saves the cycle and consumption of chemicals.

Description

technical field [0001] The invention relates to a detection technology for measuring La element by a max-type X fluorescence spectrometer, in particular to a method for measuring La element in aluminum wire by using a spectrometer. Background technique [0002] At present, most of the methods for detecting La in aluminum wire / aluminum-based alloys use ICP inductively coupled plasma spectrometer detection technology. The detection technology of ICP inductively coupled plasma spectrometer needs to dissolve the sample. The early sample processing is more complicated, the detection cycle is longer, and the influencing factors in the sample detection process are complex. For example, the La element content of 5# sample is determined to be 0.011%, which is about 42.1% different from 0.019 in chemical wet analysis, and the analysis result is inaccurate. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an accurate and ra...
