Notes:
The concepts of coherence and composition paths, originally developed for multicomponent chromatography, are used to establish a simple theory of transport in systems with precipitation and dissolution in the course of multicomponent, single-phase flow in permeable media. Composition route construction in phase diagrams in combination with distance-time diagrams yields concentration profiles without recourse to trial-and-error procedurs. Detailed results are given for systems with three ions A, B, and X and up to two precipitates AX and BX. The extension to systems with additional, nonprecipitating species is described. The new approach confirms most conclusions of Bryant's earlier theory, removes assumptions stipulated in the latter, and is simpler to handle.
