Abstract

The presence of heavy metals in environmental and industrial hygiene samples poses significant health and environmental risks, necessitating accurate and efficient extraction methods for subsequent analysis. Ultrasonicassisted leaching has emerged as a powerful technique for extracting heavy metals from various matrices due to its simplicity, efficiency, and minimal solvent consumption. This article explores the principles, applications, and advantages of ultrasonic-assisted leaching in the context of heavy metal analysis from environmental and industrial hygiene samples. By utilizing high-frequency sound waves to induce cavitation and enhance mass transfer, ultrasonic-assisted leaching accelerates leaching kinetics, reduces extraction times, and minimizes solvent usage. This methodology is compatible with a wide range of sample matrices and can be easily integrated into automated sample preparation workflows. Following leaching, heavy metals are quantified using analytical techniques such as atomic absorption spectrometry (AAS), inductively coupled plasma optical emission spectrometry (ICP-OES), or inductively coupled plasma mass spectrometry (ICP-MS). Ultrasonic-assisted leaching finds applications in environmental monitoring, industrial hygiene assessments, waste characterization, and occupational exposure assessment. Continued research in this field is expected to further enhance the applicability and effectiveness of ultrasonic-assisted leaching in heavy metal analysis and environmental management.
