Our primary goal in this research is to investigate the reaction mechanisms and important non-biological variables which affect the partitioning of microcontaminants in aqueous systems between the bulk solution and solid-phase adsorbents. The primary technique used for this work is cylindrical internal reflection-Fourier transform infrared (CIR-FTIR) spectroscopy, in conjunction with wet chemical adsorption studies, and electrophoretic mobility and acoustophoresis measurements. We have had limited success in attempting to develop CIR-FTIR spectroscopy into a quantitative technique for the study of suspensions. Difficulties are related primarily to the nature of the arrangement of suspension particles around the CIR crystal and the design of the CIR optics. Because of the importance of particle-particle interactions and agglomeration in these more concentrated suspensions, we are using a new technique, acoustophoresis, to aid in evaluating the interparticle forces which determine the arrangement of these particles. These interparticle forces affect particle-particle organization not only in the CIR cell but also in the environment. This report discusses our initial efforts to utilize acoustophoresis instrumentation. 7 refs., 4 figs.
