Surfaces and interfaces are ubiquitous in the environment. Nonlinear optical (NLO) techniques, such as second harmonic and sum frequency generation (SHG and SFG, respectively), allow for highly sensitive surface measurements under environmentally relevant temperature and solute concentration conditions. In this work, we present three experimental studies that demonstrate how NLO methods can be used to investigate the interaction of manganese and chromate ions with environmental interfaces. The environmental implications of this work are discussed in the context of understanding heterogeneous processes in geomedia.
