摘要：

The use of ultrasonic energy to bring biological matrices into solution was studied. Sonication of aqueous suspensions of biological samples in 1% H2O2/0.5 M H2SO4 mixtures with a commercial 20-kHz probe yielded complete dissolution for a range of materials within 40 min. The physical and chemical processes occurring during sonication were investigated. Analysis of NIST SRM's oyster tissue and pine needles for Cd, Sr, Cu, Zn and Mn by ICP-OES showed good agreement between experimental and certified values. Advantages of the method include shortened dissolution times and lower reagent requirements.
