基于LIBS技术的钢丝表调液Zn元素快速检测分析
Rapid detection and analysis of Zn element in steel wire surface adjustment liquid based on LIBS technology
摘要
Abstract
To achieve online rapid detection of steel wire meter liquid adjustment,filter paper enrichment was used to verify the feasibility of the enrichment method for steel wire meter liquid adjustment.On this basis,the influence of pH value on the detection results of laser induced breakdown spectroscopy(LIBS)technology was studied,and calibration curves were established by matching the pH values of standard samples to invert the Zn element in 7 surface adjustment liquids of a certain steel wire factory.Theoretical analysis and experimental verification were carried out.The results show that when Zn concentration is the same,there is a significant difference in LIBS spectral intensity with the change of pH value.The pH values of different types of steel wire table adjustment liquids cover-0.91～8.95.For samples with different pH values,the correlation coefficients are all above 0.98.The average relative error between the LIBS technology detection and the inductively coupled plasma mass spectrometry detection results of the seven types of adjustment liquids is-13.09%.LIBS technology combined with pH value matching to establish calibration curves can achieve rapid and accurate measurement of Zn element in steel wire surface adjustment solution.This study provides a methodological basis for the application of LIBS technology to the online detection of key elements in surface adjustment liquid during steel wire production.关键词
