Evaluation of ultrasonic-assisted digestion procedure for copper, zinc and iron determination in seaweed

Evaluation of ultrasonic-assisted digestion procedure for copper, zinc and iron determination in seaweed

Ultrasound-assisted digestion is a promising alternative digestion method in the analysis o f solid samples for trace metals determination. In this work, ultrasoundassisted digestion (UAD) was evaluated as a digestion method for metals measurement in seaweed by flame atomic absorption spectroscopy (...
