Rotating disk reactor LERDR350

The LERDR350 permits reaction rate studies between various fluids and solid surfaces. The apparatus consists of a rock disk rotating at constant velocity in a hermetic chamber filled with reactive fluid. The amplitude of mass transfer and chemical reactions can be adjusted with rotational speed and experimental temperature.

Bulk reactant concentration is measured at specified time intervals via atomic absorption spectrophotometry. The global reaction rate at a given angular velocity is computed from the change in reactant concentration over time. The experiment is then repeated at different angular velocities to obtain the reaction rate as a function of angular velocity. Additional experiments at different temperatures or different test fluid concentrations can also be performed to obtain the full rate law for the reaction system.
