摘要
原子吸收光谱法是检测食品中重金属的重要技术,但其分析过程中存在物理、化学和仪器干扰等多种干扰因素.本研究对这些干扰因素进行了深入分析,并提出了相应的对策,包括优化仪器参数、采用先进的样品前处理技术、应用新技术如流动注射分析、微波消解和高分辨率连续源原子吸收光谱技术等.通过这些策略的实施,可以有效降低干扰,提高检测的准确性和灵敏度,为食品安全监测提供有力的技术支持.
Abstract
Atomic absorption spectrophotometry is an important technique for detecting heavy metals in food,but its analytical process is subject to various interferences,including physical,chemical,and instrumental factors.This study conducts an in-depth analysis of these interference factors and proposes corresponding countermeasures,including optimizing instrument parameters,adopting advanced sample pretreatment technologies,and applying new techniques such as flow injection analysis,microwave digestion,and high-resolution continuous source atomic absorption spectrometry.The implementation of these strategies can effectively reduce interferences and improve the accuracy and sensitivity of detection,providing strong technical support for food safety monitoring.
