Kinetic justification of the solubility product: Application of a general kinetic dissolution model

Article Abstract:

A study demonstrates how the dissolution of euhedral faces of crystals are governed by the nonlinear quantity represented by the solubility product, using a simple, feldspar-like model and the crystal-based reaction mechanism for water-rock kinetics. The kinetic approach justifies the use of a nonlinear solubility product even in a kinetic model that has the arrival and departure of molecular units independently controlled by their respective concentration in solution and their bonding on the surface.

Discharge-flow kinetics measurements using intracavity laser absorption spectroscopy

Article Abstract:

Intracavity laser absorption spectroscopy (ICLAS) is demonstrated as a feasible detection method for trace species in a discharge flow tube. The sensitivity of ICLAS, coupled with the versatility of the discharge flow technique, suggests that intracavity absorption spectroscopy will be a useful technique for kinetics measurements on free radicals and other reactive species.
