We present the first study of the effect of interactions on phenomena associated with trapping of diffusing particles. Specifically, we consider a single trap and a two-component mixture of T and F particles where only the T particles can be trapped. We show that the trapping rate Q is controlled by the ratio R=cF/cT of the T and F concentrations, and satisfies the scaling law QR2f(tR4). For t below a crossover value t× (which scales as R-4), we recover the conventional result Qt-1/2. Above t×, we find new and anomalous behavior Q(1/R)t-3/4.. AE
