Assessing the greenness of optimized ultrasound and infrared assisted extraction through analytical metrics

Advances in Sample Preparation, 2023
ABSTRACT: Sample preparation involves a critical step due to the high organic matter content that implies its decomposition, prior to analysis. Two alternative analytical strategies for sample preparation employing diluted HNO3 were optimized and compared, assisted by ultrasound (USAE) and infrared (IRAE) radiation.
