Increasing concern over atmospheric environmental problems has necessitated the design and development of new analytical techniques in order to introduce alternatives to the presently employed methods. The use of solid sorbents for collection of pollutants in air has gained general acceptance, and criteria for this type of system have often been presented. In general practice, solid sorbents are subjected to a desorption process in order to prepare an analyte solution prior to an analytical detection procedure of choice. Therefore, in general, the solid sorbents employed are designed to provide physical and chemical characteristics for efficient takeup of analyte and yet allow effective desorption procedures. This results in a high overall recovery value necessary for required accuracy. Collection of atmospheric H/sub 2/S on a Cd(II)-exchanged zeolite as a solid sorbent and application of several analytical techniques as diverse as X-ray fluorescence spectrometry, combustion analysis by nondispersive infrared (IR) measurement, diffuse reflectance Fourier transform infrared (FTIR) spectrometry, visible spectrometry, and photoacoustic spectrometry on both intact solid sorbent and its leached solution after conversion to methylene blue have been studied. The present paper reports the initial data on a novel sampler-sensor that uses a filter paper pretreated system as a solid sorbent sampler having an air channel in the shape of a planar spiral which gives a direct visual readout of low levels of H/sub 2/S.
