The DA equation is based on the DR equation and can be used to more effectively linearize the adsorption data and overcome the problems of characterising materials which give rise to curved DR plots.
The DA equation is given by:
W/W0 = exp {− (A / βE0)n}
Where n is determined by fitting experimental data to a linearized form of the equation.
