N-benzoyl-N-phenyl-hydroxylamine dissolved in ethyl acetate was employed as a ligand for the solvent extraction of copper. Ultrasonic emulsification was shown to be effective both in the extraction of copper from an aqueous phase into ethyl acetate a

Lead poisoning is recognized as a major environmental health risk and blood tests are used to assess occupational or domestic exposure to lead. Evidence has suggested that salivary lead concentration is closely related to recent lead exposure and may

Fish gill mucous is used as a nondestructive biomarker for the detection of heavy metals by sono-square-wave anodic stripping voltammetry (sono-SWASV). The mucous sample was obtained by gently rinsing the rainbow trout (Salmo gairdneri) with a soluti

In this paper, square wave anodic stripping voltammetry (SWASV), synergistically coupled with an ultrasonically enhanced preconcentration step has been shown to yield a quantitative determination of lead and cadmium in human saliva at a membrane free

Sonoelectroanalysis is applied to the detection of copper bound within human blood protein and whole blood. A solid glassy carbon electrode in a face on horn-to-electrode arrangement was first used to obtain silent and insonated square-wave anodic st
