摘要: Publisher Summary This chapter discusses the piezoelectric crystal detectors for environmental pollutants. A block diagram of simplest typical experimental setup is presented. The housed in detector cell and driven by a low frequency transistor oscillator. monitored counter modified digital-to-analog converter. Piezoelectric are used detection dissolved gases aqueous solutions. Ammonia hydrogen sulfide determined utilizing gas-permeable membranes to isolate from solution. catalytic effect bromide on oxidation iodine iodate permanganate acidic medium utilized determination with detector. Iodide solution means silver electrodes connected normal TTL metal ions adsorptive Fe(III) as phosphate studied.
