The immobilization of chelators to solid supports has recently gained renewed interest due to the increasing biomedical and environmental applications made possible by these molecules’ ability to bind Fe(III) and other metal ions. The uses of immobilized chelators have expanded to include the treatment of metal overload in serum, the...
Simulations of combustion and reacting flows often encounter stiffness in the equations governing chemical kinetics. Explicit solvers for these ordinary differential equations offer low computational expense, but typically cannot efficiently handle stiff systems. In contrast, implicit methods demand greater expense but offer unconditional stability—as a result, most reactive-flow solvers rely...
A method for measuring chemical reaction rates in order to
distinguish between different reaction mechanisms is presented.
This method was used to study zero -, first- and second -order reactions
by analyzing the output response to a sinusoidal input of
reactant concentrations in an isothermal continuous stirred tank
reactor.
The...
A photon-counting technique which provides direct digital read-out
of data has been developed and evaluated for the reaction rate determination
of glucose. The enzyme catalyzed oxidation of glucose
to gluconic acid and hydrogen peroxide with the subsequent reaction of
hydrogen peroxide with excess iodide to produce tri-iodide is followed
by...
