✦ Synopsis

X method for the deterinination of ammonia and hydrogen sulfide in aqueous solution is presented. This method involves the use of a gas-permeable membrane which isolates the piezoelectric crystal device from the solution yet allows the desired gases to pass. Concentrations up to 0.45 31 for NH, 'and 9 -lo-' M for HIS give linear calibration curves of concentration \s. frequency change.

Sonotrodes were made by implanting a working electrode into the tip of an ultrasonic horn. These were investigated for the use in ultrasound assisted anodic stripping voltammetry (ASV) of Pb 2+ and Cu 2+ in aqueous solutions to which Hg 2+ was added to permit the formation of lead/ copper amalgam in
